Roger Cicala and the LensRentals team recenlty opened up a Sony FE 135mm f/1.8 GM and came away quite impressed (even though the lens was returned with a serious issue).
This is a very well made lens. It IS built like a tank with robust magnesium alloy barrels, lots of long thick screws holding things together and nothing flimsy to be seen. The electromagnetic focusing motors, which were a weakness a few years ago, are now built like you could pull trucks out of ditches with them.
 
The more subtle stuff, things like the neatly laid out flexes and reassembly markers, indicate to me that a lot of care was taken in designing this lens. Nothing has that ‘we can stuff that in this nook over here’ look.
 
It’s a great lens optically that is very well built.
LensRentals takes great care in ensuring your rental arrives in tip-top condition. Be sure to keep them in mind for your rental needs.

After putting the Sony 135mm f/1.8 GM through LensRentals MTF tests, Roger Cicala immediately sent a note of congratulations to some of his Sony contacts. Why? As Roger puts it in the LensRentals Blog post:
In the center, that’s the highest MTF I’ve seen on a non-supertelephoto lens. The highest. Let’s put particular emphasis on the purple line, which is 50 lp/mm. That’s a higher frequency than any manufacturer tests (that we know of), appropriate for fine detail on the highest resolution cameras. We would consider an MTF of 0.5 at 50 lp/mm to be very acceptable. This is hugely better, nearly 0.8 in the center. We’ve never seen that kind of resolution before.
 
The MTF drops away from the center, of course, but even at the very edges, the readings are still quite high.
The lens performed so well that Roger decided to test the lens at 100 lp/mm, something they don't usually do unless a lens is designed for 150+ MP sensors.
At 100 lp/mm the Sony 135mm f/1.8 GM has a higher MTF than most excellent primes do at 50 lp / mm. If you don’t speak MTF, basically that means this lens can resolve fine details that would be a blur on excellent lenses.
Roger would go on to say:
...in a couple of years if you are shooting a 90-megapixel camera, this lens will be the one that wrings the most detail out of that sensor. Right now it looks at your 43 megapixels and goes, “that’s cute.”

From the LensRentals Blog:
You guys have watched us gut a lot of lenses and cameras over the years. So I thought it would be fun for you to see us put one together from scratch. Compared to many of the lenses we’ve taken apart, this is all mechanical lens is rather simple: no focus motors, image stabilizers, etc. But even a simple lens is a very complex structure. This post will probably give you a good idea of how much mechanical design is required to make even a very basic lens.
 
The lens is also unique; it’s a prototype C-4 Optics 4.9mm f/3.5 circular fisheye. It’s a massive lens giving a 270-degree field of view, meant for immersive video and specialty shots. To give you an idea of what 270 degrees means, the lens sees behind itself. An ultra-wide 15mm fisheye lens gives a 180-degree field of view while an 11mm rectilinear lens is less than 120 degrees.
 
The closest thing that’s existed to this is the 1970s classic Nikkor 6mm f/2.8 fisheye, which gave a 220-degree field of view, weighed 5 kg, and can be rarely found for $100,000 and up these days. The C-4 optics lens weighs every bit as much as the Nikkor, but should be far sharper, have less distortion and vignetting, and cost somewhat less than those do today. (‘Somewhat’ being defined as ‘less than half’.)
 
So let’s put stuff together!

LensRentals has posted a teardown of the Sony FE 400mm f/2.8 GM OSS Lens.
 
From the LensRentals Blog:
So what did we learn today? Really, not a lot. The Sony 400mm f/2.8 G is exactly what we expected; a very solidly built lens that is everything construction-wise you would hope for in a big beast of a super telephoto that costs $12,000. It has excellent weather sealing, heavy-duty engineering between the barrel segments, a very solid chassis, and components that all appear up to the task.

Roger Cicala has posted the LensRentals teardown of the Nikon Z 7. Here's what they found:
This is not marketing department weather resistance. This is engineering department weather resistance. Anything that can be sealed has been sealed. I’m impressed, and I will say for future cut-and-paste blurbs: this is as robustly weather sealed a camera as we’ve ever disassembled.
 
I don’t believe in weather resistance myself. I believe like life; water will find a way. I believe in plastic baggies and rubber bands. I am, however, a great believer in the idea that if you claim to do something, then [you'd better] do it right. This is done right.
 
I’m impressed by the very solid construction of the chassis and IBIS unit. I’m impressed with the neat, modern engineering of the electrical connections. Yes, I’m aware that soldered wires carry electricity just fine, but to me, there’s something reassuring about seeing neat, well thought out, 2018 level engineering.
 
I’m not here to tell you which camera is best to use or has the best performance. I’m just here to say this is a [very] well-built camera, the best built mirrorless full-frame camera we’ve taken apart. (For the record, I haven’t torn down a Leica SL.)

I’ve wanted to look inside the new Canon and Nikon mirrorless cameras since the moment they were announced, so I’m probably more excited about this than you guys are. I’m really not sure what to expect. Early on, when we took apart a Sony A7R, we were struck by how clean and straightforward mirrorless cameras were compared to DSLRs. Later, we took apart an A7RIII and found that increased capabilities led to increased complexity, although still not as complex inside as a DSLR.
 
So we expected things not to be too complicated – no mirror box, optical prisms, off-sensor AF system, etc. We know Canon cameras to have clean, even elegant, engineering; like the 5D IV teardown shows. We haven’t done a Nikon SLR teardown in quite a while (the D7000 was the last one), but their camera engineering is pretty similar to Canon’s, although being Nikon they still like to leave some soldered-wire connections here and there. So we figured that the new Canon and Nikon mirrorless full-frame cameras would be more straightforward than their SLR cameras, and perhaps Nikon set down the soldering gun and slowly stepped away.
 
But really we had no idea how things would look inside, if we might see some cool new engineering, what the weather resistance would be like, etc. So we took apart both a Canon EOS-R and a Nikon Z7 just to have a look around. (The Z will get written up as soon as I can get to it.)
See the LensRentals Canon EOS R Teardown for more information.

From the LensRentals Blog:
Canon ‘refreshed’ the ever-so-popular 70-200mm f/2.8 lens from a ‘II’ to a ‘III’ with new optical coatings and paint, but no major changes. While the price is higher than the current II, it actually is the same price as the II was sold at for most of its life. A meh moment for almost everyone except those who scooped up the ‘II’ at reduced prices.
 
I did wonder if perhaps there might be a bit more under the hood than what Canon had announced. These are arguably the most popular lenses Lensrentals.com stocks; hundreds of copies with constant turnover. Since we do in-house repairs, over the years we’ve noticed some minor upgrades that have taken place; an internal ring and some gears have changed, etc. Internally, the 70-200mm f/2.8 is also one of the ugliest bits of engineering in the Canon fleet. We can understand why it had to be that way; it’s an incredibly complex lens. But we figure this bothered Canon’s optomechanical engineers as much as it did us, so maybe they snuck some changes in.

In a recent blog post, the LensRentals team makes a simple request – "Please, don’t take our photography and video gear to Burning Man."
 
Just like Color Run marathons, photographing Burning Man is a great way to ruin [even weather sealed] photography gear. LensRentals warns that damage incurred while using their gear at the cultural event is not covered under the LensCap Protection offered (such damage is considered neglect, not accidental).

Time and time again, we've stressed the importance of having a structured, reliable method for backing up your images and keeping them safe. In its latest blog post, LensRentals enumerates how videographers can protect themselves from data loss through reliable data transfer and backup techniques.
 
From the LensRentals Blog:
By Ryan Hill
 
Two or three times a week here at Lensrentals.com, we get one of two common support calls. Scenario number one is that someone thought they transferred all of their footage over, but later found that they missed a couple of clips and need us to send them their rental cards back. If we haven’t inspected those cards yet, we’re happy to do that, but if our techs have already inspected them, that’s a problem we can’t solve. We perform a full and secure format at inspection to make sure previous customers’ footage isn’t recoverable on subsequent rentals. Once the footage is gone, the footage is really and truly gone. No amount of file recovery software can bring it back. That’s never a fun phone to call to have.
 
The second scenario is that someone did manage to transfer over all of their footage, but one of the clips was corrupted in the transfer. Typically this realization comes during the edit, after we’ve already formatted the original media. That’s an equally tough phone call. True, sometimes file corruption happens in-camera, but nine times out of ten, the file was corrupted during the transfer from the card to the computer or hard drive. These kinds of problems aren’t something you can avoid entirely. There are inherent risks in working with digital media just like there are inherent risks in working with tape or film. However, there are steps you can take to mitigate that risk and to ensure that, if a problem arises, you’re prepared to work around it.

Roger Cicala and the LensRentals team opened up Sony's latest high resolution MILC – the a7R III – to see what weather sealing design improvements have been implemented compared to its predecessor, the a7R II.
 
From the LensRentals Blog:
The Sony A7R III has been out for quite a while. Generally, it’s a superbly popular camera with excellent reviews. We were busy moving to a bigger office, and then catching up from moving when it was released, so doing a teardown wasn’t high on our list of things that needed doing. And the good folks at Kolarivision did an excellent teardown, so we didn’t feel any need to rush.
 
We’ve dealt with a number of water damaged A7 cameras in the past and have a bit more knowledge of where the leaks have occurred, so we wanted to look for ourselves. Plus, we wanted just see all the complicated goodness inside. Now that things have slowed down we decided to take a look.
 
This will end up being a useful post for those of you who need to venture out into the elements with your camera. Sony has, as they said, markedly improved the weather resistance on this camera. They also left a screaming ‘leak here’ gap in the sealing that you can probably address yourself.

From LensRentals:
 
Dear customers, Here at LensRentals, we are completely committed to delivering the absolute best rental experience for every customer, every time. In our opinion, there is only one other company in this industry that upholds the same type of standards that we hold so dear here at Lensrentals.
 
That’s why we’re so excited today to announce we’ve joined forces with our friends at LensProToGo. We’ve had a mutual respect and friendship with Paul and the entire LPTG crew since the days when Lensrentals operated out of my spare bedroom. We’re happy to have Paul join the Lensrentals ownership group and to have the rest of the LPTG team joining our family.
 
When Paul and I started in the equipment rental business over a decade ago, it was pretty scary, with each of us trying to figure out how to do this. We were respectful competitors but also helped each other, sharing what we each had learned with each other. This new partnership not only combines two great companies, it combines two great management teams.
 
For those of you who have used LensProToGo, you already know how fantastic the folks at LPTG are. Their entire team in Boston is made up of professional photographers & videographers with a passion for helping you achieve your goals.
 
LensProToGo customers will get access to the largest rental inventory in the country and the advantages that arise from a shipping location located just a few miles from the FedEx SuperHub in Memphis. Lensrentals customers will get access to an even larger staff of experts ready to offer unbiased advice and to help you craft solutions for whatever projects you have coming up.
 
Both brands will continue to exist and thrive. If you’re a LensProToGo customer, the only differences you’ll notice is a greater choice & availability of equipment, and that your shipment might ship from Lensrentals HQ in Memphis. If you’re a Lensrentals customer, you’ll soon have more options for pickup locations, and you might end up talking about your order with a staff member who has a wicked good New England accent instead of an adorable Southern drawl.
 
We’re committed to keeping what you love about each brand and only making each one better than ever. We look forward to telling you more about all the exciting things we have in store in the near future.
 
Thank you for your continued loyalty,
Roger Cicala

From the LensRentals Blog:
 
I posted an article about circular polarizing filters recently, letting you see some data I obtained for Lensrentals when they were reviewing which of the polarizing filters were among the best. I concluded that they all polarized light really well. I also said that none of the CPs I tested seemed to cause optical problems at 200mm and under, that some transmitted more light than others, and that you could tell that just by looking at them.
 
Which brings me to Roger’s First Rule of This Blog.
Rule #1: I am not responsible for what someone else says I said. If I say something wrong, I’ll correct it. If they say I said something I didn’t say to drive some click-bait, THEY said it. Not me.
A bunch of people wanted hardness tests, scratch resistance tests, light scattering tests, torque tests, and a 5-year failure rate. I want a pony to ride on my yacht. Sadly, none of the above is happening.
 
A whole lot of other people asked me to test something out of the price range I was examining; mainly they wanted to see how inexpensive filters did. That was reasonable, so I bought a couple of inexpensive CP filters and repeated the tests on them. You will need to look at the last article on the $100-$200 range filters to get some perspective before looking at this.

So, a while back I wrote a not quite complete article on UV filters. To do that, I had to buy new testing equipment and learn to test filters. This was not what I wanted to do when I grew up. But somebody has to do it, and I did get to buy new toys.
 
More importantly, Tyler (Who handles the purchasing) asked me why, many years ago, I chose the Circular Polarizing filters that Lensrentals stocked. A better person than me would have confessed that I’ve never known the first thing about Circular Polarizers; that I just bought the most expensive to be our ‘best’ and the cheapest to be our ‘basic.’ But instead, I just said, “Well, we should do some scientific-type testing and a more thorough evaluation now.”

From the LensRentals Blog:
We’ve had a number of fun, new lenses to test this summer and one I was pretty eager to get to was the Sigma 14mm f/1.8 Art, for a couple of reasons. First of all, it’s a 14mm lens that has a wider aperture than f/2.8, and that’s certainly interesting. Second, it’s a new Sigma Art prime lens, and those have been spectacular. So I begged and threatened and got the first ten copies for some bench testing before they went in stock.
 
As always, these are optical bench tests, so take them for what they’re worth. It is not a lens review because I don’t review lenses. That’s what photographers do. I test them, because, well, I’m a tester. Test results should tell you if the lens is worth consideration and further investigation, not that you should run out and buy it. I don’t make any suggestions about what you should run out and buy because I have no idea how you shoot or what’s important to you. But if the resolution is important to you, then read on.
 
As always, these are the results of 10 tested copies; each tested at four rotations with 84 data points. For those who don’t speak MTF, the easy version is higher is better, and dotted and solid lines of the same color close together are better.

From the LensRentals Blog (article by Roger Cicala):
Well, I’ve written (with some misgivings because it has a tendency to create rioting in the streets) several articles about protective filters. Articles that say sometimes you shouldn’t use protective filters, and others that say sometimes you do need to use protective filters, and most recently, one showing how cheap filters can ruin your images.
 
Because no good deed goes unpunished, the result of all this has been about 762 emails asking if this filter was better than this other filter. I answered most with I don’t know for sure because I don’t test filters and, of course, everyone asked me to test filters. To which I said no. Life is too short.
 
Even Drew, who I sort of work for, asked me to test filters and write up the results. I told him I’d need at least $1,500 worth of filters to make even a basic comparison, which I thought would end the conversation. But next thing I know Drew was ordering $1,500 worth of filters. I told him I’d get around to it some day.
 
Then Brandon, who sort of works for me, emailed and said he could build a gadget to measure transmission and polarization through filters if I wanted to start testing filters. I told him I’d get around to it some day. Then he said it would have lasers. "Someday" became "right now" because of lasers. We’ve got lots of cool toys at Olaf and Lensrentals, but no lasers.
 
So today I will show you the results of testing a couple of thousand dollars worth of clear and UV filters using a couple of thousand dollars worth of home-made laser light transmission bench and a lot of thousand dollars worth of Olaf Optical Testing bench. So that we get this out of the way now: please don’t email asking me to test your favorite $6 UV filter. I’ve opened up Pandora’s Filter Box with this, and it’s already going to lead to way more work than I wanted to do. I’ll maybe do some testing of circular polarizing filters later, and maybe some testing of variable neutral density filters after this. Maybe not. I’ve got ADD, and I get bored easily. Even with lasers.
 
I like to keep these articles, well, no geekier than they just have to be. But I also want our methods to be transparent. So I’m going to give an overview of methodology in the article and put the geekier stuff in a methodology addendum at the bottom.

Yes, I’m sick of filter articles, too. But I come today not to educate you, but to mock others. Because yes, people continue to try to save a few bucks by putting a cheap filter in front of their $1,000 lens. And also because they buy what they think are good filters off of Fleabay or some used place and these filters aren’t what they think. This can particularly happen when you purchase a brand that makes different filters of differing quality.
 
How bad can it be, you ask? Well, today we’ll show you. Because someone had a 70-200mm f/2.8 lens that had been nice and sharp and then returned it because it suddenly got soft. They were kind enough to return it with their protective filter in place.
See the entire article on the LensRentals Blog.
 
Note from Sean: We've often advised site visitors not to skimp on their filter purchases. From our perspective, it doesn't make sense to invest in an expensive (often L-series) lens just to negate its high end performance with a cheap, low quality filter affixed to the front of it.
 
If you want to protect a lens and retain its image quality, be sure to use high quality filters with it, like B+W XS-Pro filters (our personal favorites).

LensRentals recently disassembled a Sony FE 70-200mm f/2.8 GM OSS and found three aspheric elements (unusual for a telephoto zoom) and uniquely designed AF system.
 
From LensRentals Blog:
As part of that Holy Quest, we wanted to take a look inside the FE 70-200 f/2.8, because, well, that’s what we do. They’ve been in such short supply, though, we just haven’t been able to take one apart. But a customer was kind enough to drop one of ours, jamming the focusing system. We decided the opportunity to do a repair/teardown was too good to pass up.
 
It’s not the first time we’ve made a bad decision, and it probably won’t be the last. It ended up being the longest and most complex (6 hours) teardown we’ve ever done. If you’re interested, read along and come feast your eyes on one of the oddest lenses we’ve ever looked into. But it’s going to be a fairly long read. (Poof! There went 90% of the blog viewers.)
 
I’ll warn you now, I’m going to use words like different, odd, and weird when describing the inside of this lens, especially in the second part of this two-part teardown. Don’t misread that to mean I’m saying ‘bad’ because I’m not. Sony is the one manufacturer these days that’s trying all kinds of new and different things. I love that. Sometimes new things are better, sometimes not. But it does make them different.

The team over at LensRentals has posted a teardown of the Canon EF 70-300mm f/4-5.6 IS II USM lens.
 
From the LensRentals Blog:
As with most new lenses, a Canon 70-300mm f/4-5.6 IS II made it’s way back to the repair department for an initial tear-down. I know there’s some randomness as to what we tear down, but we have some reasons for doing these. Sometimes, like with this new Canon, it’s simply because we know Lensrentals is going to stock a lot of them and we need to take a look inside to see what is likely to break and what parts we may want to order. And other times, like with this new Canon, it’s because there’s some new technology inside we want to take a look at.
 
And, of course, almost all the time these days, there’s some aphasic marketing terminology that leaves Aaron and I looking at each other wondering “what are they trying to say that is.” This time it was “NANO USM technology.” Did that mean there were little nanobots in there focusing the motors? Or that the focus group only had to move nanometers? The problem seemed to have been compounded because some retail and review sites were claiming it had a stepper motor, a ring USM, or both. That’s what happens, marketing department, when you make up words, nobody understands without explaining what you mean.
 
Looking inside seemed a good way to clarify that. Though Canon did tell what they meant a little bit, but nobody read it. The NANO USM focusing motor made its debut in the Canon 18-135 f/3.5–5.6 IS NANO USM lens last year, but not many people talked about it. It’s also discussed in Canon’s Knowledge Base NANO USM Article, but not many people read that. The NANO USM motor is a different focusing system for Canon, although manufacturers have used similar linear piezo systems.
 
And, as always, we wanted to see what engineering goodness Canon had inside that polycarbonate lens shell. We’re geeks. Sweet design pushes our buttons, and Canon lenses have had a lot of sweet engineering lately. Even though this is a consumer price range lens, the new digital focusing meter was cool, and we wanted to see if some of the impressive engineering Canon had put in their new L series lenses was drifting down to the consumer grade models.
 
So let’s tear up, I mean let’s carefully dissect, the new Canon 70-300mm IS. But first, let’s take a quick look at that nice digital readout. I can’t say it’s all that useful, but the depth-of-field-by-aperture display is a nice touch.

Several years ago, Roger Cicala of LensRentals made a few blog posts where he intimated that buying a UV/protective filter was not necessarily a wise investment in a lot of situations. At the time, lens front elements were relatively inexpensive to replace and high quality filters were costly.
 
However, many of the higher quality lenses produced over the past 5 years have featured more complex front elements, with the result of Roger feeling compelled to revisit his cost-benefit analysis of UV filter use.
 
See Roger's recent LensRentals Blog post to see if purchasing a UV filter is a wise decision for you and your lens(es).

We recently tested the Nikon 105mm f/1.4E ED AF-S lens and were mightily impressed. Optically it was better than I’d ever expected. We had idly talked about doing a teardown when stock allowed, but we got an unexpected opportunity yesterday: one of our week-old copies had some significant dust in both the front and rear lens groups. We know (like hopefully you know) that some dust doesn’t affect images, but our customers like their lenses dust-free, so we decided to open this one up and clean the dust out of it and to take a few pictures while we were doing it.
 
I try to identify where my head is whenever I write about anything, so you’ll understand when I go all fan-boy or all snarky. Like everyone else, my expectations going in have a lot to do with my impressions coming out. In this case, I told Aaron before we started that given how awesome this lens was optically that I expected Nikon’s optomechanics were going to modernize, too. Unlike previous Nikon lenses, I thought this lens would have nice, modular construction, no soldered wires running hither and yon, not so much Kapton tape holding stuff down, and maybe even some curved circuit boards. You know, like a lens from the 21st century, not like one from the 1980’s. Aaron didn’t think so.
 
Well, I was a little bit right but mostly wrong. There is some real modularity and superb construction to this lens. There were also big chunky square circuit boards and wires soldered hither and yon held down with Kapton tape. None of which has anything to do with making a lens take better pictures or making it last longer, but it does make it a pain to take apart and work on.

I like to start articles by stating my expectations, because, like everyone, my expectations going in color my opinion after seeing the results. Given Canon’s recent series of home-run lens upgrades, I expected the Canon EF 24-105mm f/4 IS II would be a superb lens. I was particularly expecting improvement at 105mm, which was the weak point of the original lens.
 
And, I usually put my conclusions at the start of an article so those of you who don’t like MTF graphs and spirited discussion about optical results don’t have to scroll down to the bottom. The new Mk II version is a bit better than the original version, but I was expecting a lot more. I wouldn’t rush out and upgrade from the 24-105mm f/4 IS if your goal is amazingly better optics. There may be other reasons to do so, but optics is not it.

I tend to not get overly excited about new releases. The last few years have seen a lot of incremental upgrades that rarely blow me away. Usually, I end up thinking the new version of whatever is better than the last version. Not “rush out to the store and buy it” better, but “consider upgrading if you use it a lot” better.
 
Canon, though, (and Sigma) have hit some real home runs with optics lately, so I was a bit excited when Canon decided to upgrade one of their weaker lenses, the 16-35mm f/2.8, to a Mark III version. And if you don’t want to read the article I’ll summarize: rush out to the store and buy it.

Roger Cicala over at LensRentals has posted an open letter thanking rental customers for making the rental company he founded the great success it is today.
 
If you've ever rented from LensRentals, you've likely appreciated their excellent customer service. They are an excellent company and, as such, an easy recommendation when rental services are needed.
 
From the LensRentals Blog:
To Our Customers:
 
Ten years ago, if you wanted to try out some photography equipment, if you lived in a large market, your local camera store would have a few beat up copies of popular lenses for rent (with a 100% deposit). For the rest of us, we didn’t even have that option. I had this great idea to start an online rental offering, no deposits necessary and shared my idea with people I knew. Almost everyone said I would get robbed blind and lose every dime I had. Almost everyone said you’d get junky, beat-up rental equipment and were wasting your money renting online. Almost everyone said that my idea would be a massive failure.
 
I say ‘almost everyone’ because a few other people thought it was a good idea, too. You guys, our customers, thought it was a good idea. We’d never met each other unless emails count as a meeting. But we trusted each other because we all wanted this to work. Because we few thought that getting to use equipment for a few days or weeks at a reasonable price just made sense.
 
Almost everyone turned out to be dead wrong and we few turned out to be right. Lensrentals thrived beyond anyone’s wildest dreams. Sure, I took risks, and the people who joined me here worked their butts off. But you guys, our customers, were our partners in proving ‘almost everyone’ wrong. Without you, it never would have happened.
 
Ten years later, saying thank you just isn’t adequate. There are no words that would possibly express my gratitude for all of you who supported Lensrentals and created our success; you folks who shared in proving ‘almost everyone’ wrong.
 
There are no words, but I believe actions are more important than words. Everyone who works here tries to show our gratitude in our actions. Whether it’s making all of our testing data public, making sure your rental arrives in better condition than you expected, drawing a dinosaur on your shipping box because you requested it, or just talking you through a difficult set-up on the phone, we want to show you our gratitude with every rental. We want you to know it’s more than just business. It’s a partnership between you and us. You’ve helped us achieve our goals; we want to make certain we help you achieve yours.
 
We wouldn’t be doing what we love to do every day without you. We want our actions, our attitude, and our service let you know, every time you rent from us, that we are grateful that you have partnered with us along this journey.

From LensRentals Blog:
If you’re like me you like to know what’s going on inside your camera or lens to some degree. They are tools, and if I want to get the best use out of my tool I need to know it’s strengths and weaknesses.
 
You may not have noticed, especially if you shoot just Canon or Nikon, but there’s been a quiet change in autofocus motors going on. Or you might have barely noticed marketing-fluff terms like ‘linear focusing’ or ‘electromagnetic focusing’ without really understanding what they meant. Even if you understood the general terms, you probably aren’t really certain how they work, or how they might be better or worse than what we’ve been using.
 
So I thought some of you might like taking a look into what might (or might not) be a big deal: the changes that are being made in autofocus motors. Today I’m going to discuss linear electromagnetic focusing motors. I may do another post about linear-piezo and ring-to-linear piezo motors later, but those are, so far, less common than the electromagnetic motors.

Roger has posted a very objective, well thought out article on lens quality and manufacturing tolerances. It's definitely worth a read if you have a few minutes to spare.
"After we published a number of posts about copy-to-copy variation, people were quick to say that this company or that needs to 'just' improve quality control. I totally agree but realize most people don’t have a clue what ‘improving quality control’ would really look like. I think they have some vague idea of hiring a guy named Joe to sit at the end of the assembly line, check all the lenses, and reject all the bad ones. Optical quality control for lenses is way, way more complicated than that."

Fresh on the heals of their Canon EF 35mm f/1.4L II USM & Sony FE 35mm f/1.4 ZA teardowns, LensRentals has now opeened up the Sigma 35mm f/1.4 Art lens to see how its construction compares to the other two.
 
If you don't have time to read the lengthy post, here's a small paragraph from Roger's conclusions that sums up the lens's construction succinctly:
"For the most part, there weren't many surprises in this teardown. We've seen how Sigma has remade themselves as a company making only superb optics at very reasonable prices in the last few years. This lens is constructed very well. There isn't the amazing heavy-duty construction of the Canon 35mm f/1.4. Instead, I'd characterize the construction of the Sigma as very efficient and carefully laid out. There's a solid metal core with other parts all connecting directly to that core. Little touches like pegs to make sure a part is inserted in the proper rotation and shields over critical parts didn't add much expense or weight, but show care was taken in the design. There's nothing in this teardown that looked like a weak point."
You can find links to the other 35mm lens teardowns at the beginning of the this teardown.

Roger Cicala over at LensRentals was curious to see how much engineering went into Canon's new EF 35mm f/1.4L II USM. So in Roger-like fashion, he tore into one.
 
As it turns out, the lens seems especially well constructed and well thought out. Roger's comments at the bottom of the teardown say it all:
"I'm sure you can tell we're impressed with the Canon 35mm f/1.4 Mk II. The weather resistance appears better than most weather resistant lenses. (As always, I'll add that weather resistance still means water damage voids the warranty.) The mechanical construction is beyond impressive. This lens is massively over-engineered compared to any other prime we've ever disassembled. It's built like a tank where it counts; on the inside. Moving parts are huge and robust. Six big screws are used in locations where 3 smalls screws are common in other lenses. Heavy roller bearings move the focusing group, it doesn't slide on little nylon collars.
 
It's also designed thoughtfully and logically. Things that will inevitably get damaged on any lens, like the front element and filter ring, are designed to be replaced easily. There are some things inside, particularly with the tensioning screws and springs, that I'm not certain I understand the purpose of, but I am certain there is a purpose. If I had to summarize the mechanical design of this lens, I would say simply that no expense was spared, no corner was cut.
 
Sometimes things are expensive because they're worth it. Sometimes they're heavy because they're so solidly constructed. This is one of those times."
Check out the entire post for the full teardown details.

Roger Cicala over at LensRentals has been busy testing out the new Canon 5Ds and now [I'm typing this with a slight cringe], tearing one apart.
 
From the LensRentals Blog:
"When Lensrentals.com first got the first Canon 5Ds and 5D sr cameras in stock, Aaron and I immediately started screaming that we wanted to take one apart. It turns out we received enough 5Ds cameras to let us have a day with one to do just that. Of course, we don't expect to find out anything amazing and revealing. We expect it will look pretty much like the Canon 5DIII and 7DII on the inside. But hey, you never know. Plus we'll be repairing these soon enough, so we might as well find our way around now.
 
If you want to do some comparisons yourself, you can compare this to our Canon 5D III teardownand Canon 7D II teardown. Or if you'd rather follow along from home with your own 5Ds go grab your screwdrivers and let's get started!"

From the LensRentals Blog:
"Like everybody else, we're pretty excited to get our hands on Canon's new 5DS and 5DS R. There are already a lot of hands-on articles about the cameras that probably have told you more than you need to know to make your purchase decision. Of course, for most of the Canon shooters who read this blog, the purchase decision was just which place you want to buy it from.
 
For me, I want some lab data to see just how much of a difference those megapixels make. More particularly, I want to see how much of a difference they make when shot through a reasonably good lens, an excellent lens, and an adequate lens. Some people want to simplify things too much and claim certain lenses are 'good enough' for the new cameras and others aren't. It's not that simple.
 
So we begged and threw temper tantrums until Drew agreed to let us have a couple of the new cameras for a couple of days testing in our Imatest lab. That was enough time for us to get a quick overview using several different sample lenses, but it will be months before we have a good database of which lenses are most capable on the new cameras."
Resolution tests included use of the Canon 300 f/2.8L IS II USM, Zeiss 85mm f/1.4 Otus, Zeiss 21mm f/2.8 Distagon T* ZE & the Canon 50mm f/1.4 USM. To find out how each lens performed when paired with the 5D III, 5Ds and 5Ds R, check out the full LensRentals Blog article.

Roger Cicala has posted about an interesting little critter he found in a recently returned Canon EF 24-105mm f/4L IS USM.
 
From the LensRentals Blog:
"I've been blogging about testing and taking apart camera equipment for almost a decade. Lensrentals.com has many thousand lenses these days, and they all get used frequently. When you have lots of lenses and they get used frequently, stuff gets inside them.
 
Usually the stuff that gets inside is dust. Our repair techs open up and clean dust out of more than 100 lenses a week. Not because the dust matters a bit in a photograph; it doesn't. But because people still seem to think it does. People also, for reasons I can't understand, seem to think that weather sealed lenses are less likely to get dust in them than non-weather sealed lenses. I'm not sure why they think this, but they do.
 
Sometimes the stuff that gets inside them is interesting and we get to blog about it. We found a spider, complete with web, inside a lens once and yesterday we got to add a new item to our 'found inside lenses' collection; a nice, fat, fly. And not just a fly inside a lens, but one way down deep inside a weather sealed lens. So deep that it took 4 hours of work to get it out."

Roger Cicala of LensRentals has posted a partial teardown of the Tamron 15-30mm f/2.8 Di VC USD lens.
 
His takeaway? Tamron's latest wide-angle zoom is well built but isn't nearly as modular as most of Canon's newest lenses; fixing one at home is not necessarily recommended because of the complex nature of the lens's construction.
 
Check out the LensRentals Blog for the well-illustrated (and equally entertaining) partial teardown.

From the LensRentals Blog:
"Every once in a while we notice something, because of the large quantities of cameras and lenses we buy, that we think people should be aware of. This particular issue won't affect our renters; we've sent the affected cameras back. It may not affect very many people at all, since this is from a relatively small sample size. But I still think it worth mentioning.
 
The bottom line is that 4 of the Canon T6s and 2 of the T6i cameras we received had to be sent back because of a defect in the sensor stack (the layers of filter glass over the sensor). This is out about 10 copies of each; the others were absolutely perfect."
See the entire article on the LensRentals Blog.
 
We checked our own Canon Rebel T6s review camera and there was no indication of the defect. We have no idea how widespread the issue is, so be sure to check your own Rebel T6s / T6i cameras upon receipt.

From the LensRentals Blog:
"Most of you know I've been very impressed with Sigma's new Art lenses. Their 35mm f/1.4 Art I still think is the sharpest 35mm prime lens made. The 50mm f/1.4 Art is also superb.
 
When I heard about the Sigma 24mm f/1.4 Art lens, I had some mixed emotions. I was excited that we might get a 24mm lens of similar quality to their 35mm. But the logical side of me thought that perhaps Sigma had bitten off a bit more than they could chew this time. Designing a wide-aperture 24mm lens is much more difficult than designing a fast 35mm lens. Even the best 24mm f/1.4 lenses (I consider the Canon 24mm f/1.4 L to be the best current offering, although that's arguable) still have distortion, aberrations, and some edge softness.
 
But when our first five copies of the Sigma 24mm f/1.4 arrived, I swiped them from intake and took them over to the testing lab for a quick look and MTF testing on our optical bench. We already had results from the Canon 24mm f/1.4 L, the Nikon 24mm f/1.4 ED AF-S, and the Rokinon 24mm f/1.4 lenses in our database to compare them to."
