Future Firmware Plan: RF 70-200mm f/2.8L IS USM lens
Thank you for using Canon products.
It has been confirmed that when using the RF 70-200mm F2.8 L IS USM to perform AF shooting to capture a subject at close-range with the focus distance approximately set to the Tele-end (200mm), the image may become slightly front-focused.
New firmware with improved focus accuracy is scheduled for release in the beginning of Jan. 2020, and once the preparations are completed, we will post the information on our Web site.
Note: New firmware being released at this time is for lenses equipped with firmware version 1.0.5 or earlier. The lens firmware version can be checked in the camera’s menu.
The lens experts at Optical Limits posted a Canon RF 35mm f/1.8 review.
The Canon RF 35mm f/1.8 STM IS Macro is one of the less expensive lenses for the Canon EOS R full frame mirrorless system. At less than or around $500/€500 it is much more affordable than the so called “boutique lenses” for the EOS R.
From their conclusion:
The Canon RF 35mm f/1.8 STM IS macro may not be the sexiest lens around but it is capable of delivering very high-quality results. Images are sharp in the center straight at f/1.8 and the corners are just marginally soft. There’s a substantial increase in quality at f/2.8 and the resolution is truly impressive medium aperture settings. Image distortions, as well as lateral CAs, are low. The same can’t be said about the native vignetting which is rather extreme at maximum aperture. However, auto-correction comes to the rescue so most users will probably just notice a slightly elevated light falloff at f/1.8. The bokeh is generally nicely rendered with a silky background blur and smooth out-of-focus highlights. The foreground blur is less ideal though. Bokeh fringing (LoCA) is present at large aperture settings but that’s hardly surprising. However, a more ugly effect are focus shifts when stopping down (RSA) which seems to have a negative impact on AF accuracy as well.
Here is a Canon RF 85mm f/1.2 DS review by YouTuber Artaius.
If you wonder what the “DS” stands for it’s for “Defocus Smoothing“, an optical technology exclusive to Canon. As you might already have figured out, Defocus Smoothing is about blurring out the background, getting a nice bokeh effect, and everything creative you can do with out-of-focus items. Another boutique lens for the Canon EOS R full frame mirrorless system.
The Canon RF 85mm f/1.2L DS (Defocus Smoothing) is the closest Canon will ever get to making a Lensbaby lens – its bokeh is just next-level wow. The question is, will it replace the standard RF 85mm f/1.2 as my favorite lens for the Canon EOS R? I put them through some side-by-side shooting comparisons to show you exactly how unique the bokeh is on this lens, and to help you decide whether it’s worth that 3K price tag. If you want to know the difference between the two lenses, this Canon RF 85mm f/1.2 DS review is for you!

Unfortunately this optical marvel is not an inexpensive lens: it sells for $3,000.
Dustin Abbott posted a set of Canon RF 50mm f/1.2L review sample pictures.
The Canon RF 50mm f/1.2L is one of the “boutique lenses” for the EOS R full frame mirrorless system, i.e. a lens made to show off the capabilities of the RF mount. No reviewer had ever to be unhappy with the performance of this lens.
Dustin Abbott says:
Canon has also started to deliver on what was clearly the greatest strength of the platform – the new RF mount and all its potential. While the bargain lenses for the RF mount are still few (though thankfully some third party support has started to come), Canon has delivered a number of their very best lenses yet on the RF mount…and one of those is the Canon RF 50mm F1.2L, which is one of the best performing 50mm lenses, well, ever. It’s large, heavy, and expensive, but is also one amazing piece of kit.
Improving your photography is hard, mainly because lots of other photographers give wildly varying advice, based only on their own preferences. I think by far the best way to take more photos YOU like, is to study others you’ve taken in the past that you’re proud of, and work out how to bring those learnings to your future images. That’s what I do with my photos in this video :)

It only really matters what you think of your photos. But do you know why a good photo is good and a bad photo is bad? Understanding this can massively help you improve your photography.
This professional Canon EOS R body is said to play in the same league as the EOS-1D X series, i.e. the most professional tier in Canon’s gear lineup. This makes more sense than you might think at first glance. Given how committed Canon is to the EOS R system, an EOS R body with hybrid lens mount isn’t that unlikely in our opinion. And even if it is an engineering challenge, and for sure it is, Canon has the means and skills to build it.
We have been told (thanks) that the professional EOS R body with hybrid EF/RF mount will have a moving sensor, i.e. a sensor mounted on a mechanical system that can move the sensor forth and back to suit the different flange distance of EF and RF lenses (the distance between the lens mounted on the camera body and the camera’s image sensor).
We guess a moving sensor is the most feasible engineering approach to build a camera with hybrid EF/RF lens mount. Other technical solutions appear to be more difficult to realize. Given that you need to change the distance between the lens and the image sensor, what else could you do? Maybe moving the lens mount back and forth from the camera body? Doesn’t seem to us to be the better approach. Other feasible engineering approaches? Can’t think of any. I’m looking forward to spot a Canon patent application for a moving sensor.
