Just posted: Canon EOS R7 Review
Sometimes you need to call a long term project finished. While I'll call the R7 review that, I expect udpates to go on long into the future. Minimally, I hope to add some more complete camera comparisons.

This is a valuable feature.
Working through the Canon EOS R7 and Canon EOS R10 reviews, I just crossed the buffer capacity testing line item off of the to-do list and thought I'd share the results here.
The question was: Does a fast memory card make a difference in Canon EOS R7 performance?
Let's create some datapoints.
The Canon EOS R7 15 and 30 fps continuous shooting modes were tested using manual mode (no AE time lag) using ISO 100, a 1/8000 (or 1/16000 electronic) shutter speed (no waiting for the shutter operation), a wide open aperture (no time lost due to aperture blades closing), and manual focus (no focus lock delay). The image was black for the smallest file size, the battery was near full charge, and the specified freshly-formatted fast memory card was loaded.
In the table below, the V90 and V60 indicate the minimum write speed specifications for the memory cards used in the test. You care about the minimum write speed when photographing (or during movie capture), and fast card reading is always associated with fast writing.
Specifically, these tests used the Lexar 256GB Professional 2000x V90 300 MB/s UHS-II SDXC (high performance option) and Lexar 256GB Professional 1667x V90 250 MB/s UHS-II SDXC (great value, still fast option) memory cards. The first two sets of tests were so fun that I added a reasonably fast UHS-I V30 card to the chart.
The numbers indicate the image count at buffer full — the first pause in continuous shooting.
Shutter/RAW Type | V90 | V60 | V30 |
Elec RAW | 69 | 61 | 61 |
Elec CRAW | 125 | 125 | 125 |
1st Curtain RAW | 152 | 101 | 80 |
1st Curtain CRAW | 237 | 235 | 232 |
Sec to write buffer | 8-12 | 12-15 | 12-32 |
Breaking it down — what do those numbers tell us?
First, those of us who need the camera fully ready as fast as possible or need to review the last-captured image immediately after shooting a long burst (and those of us who are impatient) will want a faster card for the considerably faster buffer clearing ability.
Photographers selecting the RAW file format will notice the performance benefit of a V90 card, but the V60 card benefit over V30 is limited to the 1st curtain RAW mode — and there is a noticeable difference.
Those shooting in CRAW format will not notice an increased continuous image capture count from the faster card.
The CRAW file format is made attractive by these numbers, and those shooting in JPG format will enjoy a considerably higher number of images captured before the buffer full condition.
A vast number of memory cards are available, and they have varying speeds, but these tests give us a look at this camera's performance.
What about the R10? Does a fast memory card make a difference in Canon EOS R10 performance? Here is the that chart:
Shutter/RAW Type | V90 | V60 | V30 |
Elec RAW | 39 | 25 | 25 |
Elec CRAW | 109 | 93 | 77 |
1st Curtain RAW | 65 | 35 | 30 |
1st Curtain CRAW | >780 | >340 | 165 |
Sec to write buffer | 2-3 | 5-6 | 4-10 |
With few exceptions, the faster card provides more images before the buffer full pause and a shorter time until the buffer is clear.
I became bored after capturing a huge number of V90 and V60 1st curtain electronic shutter CRAW format images and didn't complete those tests. The camera appeared to support that frame rate indefinitely.
Again, the CRAW file format appears attractive by these numbers, and those shooting in JPG format will enjoy a considerably higher number of images captured before the buffer full condition.

Resolution test results are now available on the Canon EOS R7 and Canon EOS R10 pages.
The R7 results appear clean, showing the extreme pixel density working well.
The R10 results appear especially sharp, including a bit of moiré.
A growing number of cameras can be compared using the Canon RF 85mm F1.2 L USM Lens test results, and many more can be compared using the Canon EF 200mm f/2L IS USM Lens test results. Use f/4 or f/5.6 to reach the lens's optimal image quality.
Here are some comparisons to get you started:
EOS R7 compared to the 5D Mark IV
EOS R7 compared to the 7D Mark II
EOS R10 compared to the Rebel T7i/T8i

Sharp lens.
Note that the severe barrel distortion at the wide end of the focal length range will require correction most of the time.

The Canon EOS R10 is here, and it is time to set up this camera for use. Following are the 46 steps taken to prepare an out-of-the-box EOS R10 for use.
I make additional menu and other setting changes based on current shooting scenarios, but this list covers my initial camera setup process.
To copy this configuration means you intend to shoot as I do - including in RAW-only format. While this setup works great for me, you should adjust the setup to your needs.
If you can't remember your menu setup parameters, keeping an up-to-date list such as this one is a great idea. Anytime the camera is set to the factory state, such as when being serviced or when acquiring an additional camera, you will be ready to create your setup quickly, while ensuring that an important setting is not omitted. If you purchase another same or similar camera, setup will be fast and identical.
