Of course, if there’s going to be a fly in the lens, it’s going to be way deep inside where it’s really hard to get to. I don’t know why flies do that, but I promise you they do. You never see a fly just under the front or rear element. They get into the deepest groups, leaving little fly parts all over, and usually, get smushed by the zoom or focus element.Read the entire article on the LensRentals Blog.
“After years of our customers requesting a video tripod that could support heavier payloads for things like teleprompters or beefy camera rigs with long lenses, Benro has delivered just that. We’re super pleased with the way the product turned out and so are the pros that have been testing it for months on the road.”The carbon fiber tripod is a 2 stage, 3 section tandem style which incorporates a 100mm bowl. The leg locks are oversized levers that can be operated while wearing gloves. The lower stage leg lock lever has an additional lip, which can be opened and closed with your foot. This allows you to hold onto your camera rig while adjusting the height of the tripod. Each tripod includes a floor spreader, a telescoping pan arm and a padded carrying case.

Canon employed 1,569 people in Melville in 2017, according to the most recent state records. It must report its local employment annually to the state and to Suffolk County, both of which aided in the construction of Canon’s $500 million headquarters near Exit 49 of the Long Island Expressway.Read the entire article at Newsday.
The company moved from Lake Success to Melville in 2013 after a 25-year search for a new home. It has exceeded the employment promises made to the state and Suffolk so far. State records show Canon's employment cannot fall below 1,360 people or it would have to pay back some of the grant money and tax-break aid it has received.
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 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.
The MTF drops away from the center, of course, but even at the very edges, the readings are still quite high.
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.”You can read the entire article on the LensRentals Blog.
