The Canon EOS R is Canons latest entry into the Mirrorless cameras market, we take a closer look at what the camera can do.
The image quality of the EOS R is very good, ever since we first got our hands on the camera, we've been really happy with the image that comes out of this camera. The 400Mbps All-I codec stands up really nicely to the C200, it handles high iso's really quite well and has a really nice all-around picture.
Autofocus is of the big strengths of Canon cameras, and we love it. We use Canons dual-pixel autofocus all the time on our YouTube channel. Now, of course, the EOS R has great autofocus as well, but how good? Well in the video above, we tested the autofocus to that of the C200, and its safe to say, we're very impressed. The EOS R seemed to find faces much quicker than the C200, but didn't quite have the control pulling focus from a distant background to a relatively close face that the C200 has. The EOS R seems to snap focus to a subject, whereas the C200 smoothly transitions between subjects. We tested both EF lenses with Canons EF to RF mount adapter, and both worked just as well as each other, so if you want to take advantage of using autofocus on your existing EF lenses on the EOS R, your covered.
One thing that we've seen pop up elsewhere online, is that the EOS R has been accused of having soft footage. Now, we wanted to dig a little deeper with this, you can see all of the results in our video above, so we did various tests, as well as some comparisons to other cameras. From our tests, we've found that on default sharpness settings, which is 0 sharpness in the menus (the camera is likely still adding some form of sharpening in camera even with the slider set to 0) the EOS R is comparable the C200 and A7R III in terms of sharpness. Now it isn't super detailed like some other cameras are (like the C200) but holds up quite well. By adding +1 sharpness in the menu's we found that the camera looks much sharper, but without looking overly digitally sharpened. Once you add more than +1 sharpness, the image does really start to look oversharp, you might be able to get away with +2 sharpness at a push, but after +3 the image looks very plastic, and over sharp. We also tested whether or not sharpening in camera or post in the best option, and we found that while adding 2.5 sharpness in FCP X does give similar results, sharpening in post also sharpens the noise in your image, and sharpening in camera, doesn't seem to have this negative effect.
This really is the biggest drawback of the camera, in 4K there is some quite noticeable rolling shutter, there are no two ways around it. In 1080p it isn't quite as bad but is still there. We compared the rolling shutter to both the C200 and A7R III, both of which, performed very well.
The Crop Factor
For most people, the crop factor is a big drawback of the camera when shooting in 4K. The EOS R has a full frame sensor, when shooting stills or 1080p video the camera uses that full frame sensor. But switching to 4K gives you around a 1.7x crop, which is quite significant. But when using this camera as a b-camera to the C200 or any of Canons other cinema cameras for that matter, the crop does help the field of view for both cameras match much more nicely.
