Canon EOS R1 Review: A Flagship Made For a Select Few

The EOS R1 is the first camera I have seen that uses dual CFexpress Type B slots. This makes sense given the fast burst rates of the R1 and allows for dual recording on both cards at the same speed, unlike a single each of a CFexpress and SD arrangement. The classic LP-E19 battery makes a return but that’s just fine given the excellent all-day battery life that it provides.

Canon EOS R1 Review: How it Shoots

It becomes obvious very quickly that the R1 is a specialized sports and action camera. The burst rates can reach up to 40 frames per second (FPS) while still shooting RAW. There is a minor compromise as it must be done in Canon’s compressed RAW format but the quality is still excellent and the speeds are faster than the Nikon Z8 and Z9. The buffer is also remarkably large with the ability to shoot for over 10 seconds at 40 FPS in RAW before the camera slows. The twin CF Express cards clear out said buffer in a hurry, too.

Canon decided to go with a fairly conservative 24-megapixel sensor which is ideal for journalism but maybe not so much for studio and landscape. That said, it is a very advanced stacked CMOS sensor that has one of the fastest read-out speeds we’ve seen to date. The electronic shutter scans at around 1/350 of a second which gives a flash sync speed of 1/320 and virtually eliminates rolling shutter issues. The mechanical shutter can manage burst rates up to 12 FPS which is respectable but with a slower flash sync speed of 1/200, we wonder why Canon even kept the shutter in the camera in the first place.

Most cameras also have reduced dynamic range when using the electronic shutter but the R1 delivers similar results regardless of if you pick mechanical or electronic. As per usual, Canon bakes a little bit of noise reduction into the files, even the RAWs. Image quality is still excellent of course, with beautiful colors and rich detail, but it’s still worth pointing out.

I do personally prefer a higher megapixel count for general photography although I see why Canon would consider 24 megapixels ideal for faster shooting and journalistic photography. It is one more reason why the R1 is a particularly specialized tool.

As I stated earlier, we wanted to test the R1 in a situation that it isn’t trained for. As a recap, one of the new features in the R1 is what Canon calls the Action Priority function, which is tuned for specific sports and predicts where the focus should go for basketball, soccer, and volleyball.

It works incredibly well giving a helps to provide a very high hit rate. But what about a sport that it isn’t programmed for? Hockey provides a lot of fast action, in fairly low light, with lots of players on the ice, and all are wearing faceguards and helmets which obscures much of what Canon’s camera would be looking to identify.

I was very impressed with how it remained on players that I had initially started tracking and ignored subjects that came in between me and my target, all through thick glass around the rink as well. Canon has also simplified the focusing menu from previous cameras which, rather than taking control away, is easy to understand and effective in the field.

The R1 uses a sophisticated algorithm that can go from eyes to faces, to torsos, and my resulting hit rate was very high. This is no doubt improved with the sensor reading out so quickly and providing lots of data and calculations for the camera to focus on.

I would say the EOS R1 is the best focusing camera in Canon’s lineup and although the R3 and R5 Mark II can come close, there is an appreciable difference. This incredible hit rate is even more effective when the sport is supported by the Action Priority function so I hope to see more sports added in future updates.

Canon has thrown in all the technology it has to bear in this camera including the latest IBIS technology and a pre-capture mode that retains the first 20 images before the shutter is pressed. I found myself using the pre-capture mode religiously for hockey not only to ensure the key movement was captured but also to minimize how many thousands of images I would have to wade through later.

Canon does make a big deal about its new “AI” based in-camera editing features, although their usefulness feels somewhat fringe. The first is an up-res feature that works on JPEGs and provides a big megapixel boost. In practice, I find this feature pretty superfluous because although the megapixels grow, perceived detail does not. I would only use it as a quick aside if a certain megapixel threshold was needed by an editor or printer.

There is also an in-camera noise reduction feature that works on RAW files (to produce a JPEG) and it can be helpful in some situations. The look of the noise reduction is dramatic and detail loss is minimal. I could see a sports photographer in a rush using this feature occasionally, although in the end both up-res and noise reduction features can be done more effectively on the computer afterward.

Canon EOS R1 Review: Much Improved Video

At first glance, the R1 seems to deliver very similar video capabilities to the R3. However, it turns out that the R1 is a far more functional video platform than the R3 that came before it. 6K recording is possible up to an impressive 60 FPS using Canon’s internal recording C-RAW Light mode. The quality is decent and it is an efficient recording codec but 6K video can only be shot in a raw mode.

In a more common standard 10-bit 4K recording mode, the R1 can push up to 120FPS at an albeit sub-sampled quality level. 60FPS is oversampled, however, and quite good. CLog 2 is also present and provides a good amount of dynamic range to work with — it is our preferred Canon log profile. The R1 also comes equipped with a tally lamp which is always appreciated by presenters and the R1 gets rid of the silly micro HDMI port on the R3 and exchanges it for a proper full-size port.

Although the autofocus did sometimes drift when many players were in frame during our hokey game testing, the Canon R1 seems to be far more reliable than the R3 when it comes to following the action in video mode overall.

The Canon EOS R1 is the Perfect Camera for a Very Particular Photographer

You could argue that all flagship cameras are a niche product for a certain echelon of professional photographers– and you would be correct. However, some cameras like the Nikon Z9 and Sony Alpha 1 can handle many kinds of photography while still giving the ultimate in ruggedness and customization. Perhaps the Canon R1 is too specialized for its own good and many of the people we spoke to who tested the R1 found the R5 Mark II to be the more useful choice given its greater versatility. The R1 seems to be covering territory already trodden by the EOS R3.

That being said, the R1 is incredible at what it does. It shoots faster than almost every camera except the Sony a9 III, is rugged and reliable, and can shoot non-stop for a long time. The autofocus is reliable and good at tracking many different subjects. Canon makes excellent sports glass too, which the R1 takes full advantage of.
