Anyone here use their EOS R or RP with Leica M lenses and mind sharing their opinion regarding it?
Any issues with the corners or adapters?
Don't really care for the current RF lens line-up that are ridiculously big until they release their smaller prime lens.
Just looking for the best digital body for my rangefinder lens
Fuji sadly is APS-C
Sony is no fun
Leica digital is expensive and not as fun as film
Canon is enticing especially since I already own some EF lens.
I'm in a similar situation, with a considerable Canon EF and Leica M collection. No first hand experience yet with the Canon FF mirrorless, but what I've seen online has not been promising. Older designs have showed considerable edge color shift. I haven't seen enough to know about edge smearing but am not optimistic about it.
A while back I tried Canon's M5 (APS-C mirrorless) with a bunch of my M lenses. Everything in my inventory 35mm and wider showed some edge smearing problems. Meanwhile the Canon 22/2 was very good already from wide open compared to my Leica 21/3.4 or 21/1.4...
The reality is the best optical results are with Leica bodies... M9, M240 or M10. Or getting a Kolari sensor mod (not sure if they do more than Sony mods). Apparently the new SL2 is better M-optimized than the original SL (which from my testing was somewhat problematic with some of the Leica M wides), but of course remains an expensive option. Over at the Alt board some have shown good results with the Panasonic S1 and Nikon Z6/Z7, though it will depend on the lens and how much a given lens has been stopped down.
thanks for your input.
I think I'll buy a Leica to EOS-R adapter and go to The Camera Store and test my Voigtlander 21mm f/3.5 and 35mm f/2 on the R and RP one of these day.
Since both are modern lenses and performed well on the Sony bodies that I've owned (A7, A7RII and A7RIII), I'm hoping that it works decently on Canon.
Will also try my 50mm Summicron and 90mm Tele-Elmarit
Ultimately, I can see myself going with a small 28/50 or 24/40 AF kit to pair with the beloved 135L.

If you want the best IQ from any adapted lens, get the GFX 50R and shoot it in 35mm crop mode. I've found that the corner performance in 35mm crop mode on the GFX exceeds the corner performance on 35mm cameras like the R. I'm not sure if it's the GFX sensor's microlens design that is better suited for the sharp angle of light coming from mid-to-wide adapted lenses, but for whatever reason, it really stays sharp to the corners in crop mode.
That said, the R and RP both are great for adapted lenses. The focus peaking is wonderful and images seems to snap into focus more convincingly than with the GFX.
One thing to note is the RP only has EFCS (electronic front curtain shutter) – no real mechanical shutter. So if your intent is to ever shoot wide open in bright light (f/1.4-1.2) you should be aware that at shutter speeds over 1/500 of a second, EFCS may introduce bokeh artifacts and/or reduced bokeh. For example, at 1/4000 sec. at f/1.4 your bokeh may look like it was shot at f/2 (sometimes EFCS will even cause half the frame to have the reduced bokeh and half will be normal). The R on the other hand will let you switch from the default EFCS to mechanical shutter in the menu (LV mode "disable") and also can shoot max 1/8000 sec. versus the RP 1/4000.

thanks for the additional information. was not aware that the RP only had EFCS, so I guess the R is the way to go for fast manual focus lens if I decide to go Canon.
I thought about getting a GFX 50R last year, but TBH I wasn't overly impressed with the IQ that I got from some test shots I took with it and GF lenses. It is also almost twice the price of a EOS R and at that price range I might as well get another M240 instead. Something that I might have to consider maybe next year as I like the GFX 50R + GF 63mm 2.8 combo.
My adapter came in from Amazon, I will be heading to The Camera Store tomorrow and try out my M-mont lenses
Thank you for posting these. Shame that there is purple color changes on edges. But they look like they would be easy to fix in lightroom if lightrrom had a profile. If you have time I would be interested in focus at infinity shots
I have a voight 15 v2 if you want to try it. It is my dream size for mirrorless and works pretty well on sony a7r2. PM me - I work downtown and live West of Calgary near westhills.
I have thought about buying the R to try it but its hard to go back to 30mpx (from 42 A7r2 or 51 5dsr). And canon just does not have small lens available yet.

P.P.S You would probably get more input if you cross posted to alternate....Show more →
thanks for the reply Scott, I'll PM you for a meetup.
I'm going to try Cornerfix and Adobe Flat Field tonight to see how easy it is to fix the cyan colors. Used it in the past with the M9 and 21mm Skopar years ago with good success but time consuming.
I am a little disappointed that wide angle M lenses doesn't peform well on the EOS-R, mind buggling too as the 2 modern Voigtlander lenses perform perfectly on all Sony cameras I've owned (A7, A7R2, A73, A7R3).
I like the ergonomics of the EOS R better than Sony and EVF is better so I hope I can get this to work.
Part of the reason is the more recent Sony cameras use BSI sensors that are less susceptible to edge colour shifts, to the point where it's probably not noticeable in most situations. Microlens design will also have some influence. Pixel pitch is also a factor. For example, of the original a7 series cameras, the 36MP R exhibited more colour shift problems than the 12MP a7S.
My guess is that because the Canon sensors are not BSI, at 30MP you're in a similar situation to that of the a7R. Based on all the Canon marketing about the new lens mount allowing very large rear element designs that in turn allow light to be transmitted near perpendicularly to the sensor plane, even at the edges, whatever microlens design Canon uses is likely not optimized for light entering pixel wells at more oblique angles typical of shorter exit pupil designs found in rangefinder lenses.
I'd also like to know how good/bad edge smearing is in infinity scenes...
^thanks for the technical input, that could very well be the issue on Canon, my A7 does not exhibit the color shift on the corner but A7R does.
Quick update but Lightroom Flat field helps with the color shift easily although I'm noticing some slight green shift now.
I'm using a standard f5.6 profile for my shots though. will have to do a couple more tests and will try to get some infinity test shots with the 21mm and 35mm through the day Canon EOS R + Voigtlander 35mm f2 Ultron by Earl Dieta, on Flickr
I'm finding Adobe LR built-in Flat Field unreliable so I created my CornerFix profiles for both CV 21mm and CV 35mm (white wall shot at f/5.6) and am getting good results that I think I'm ready to say good bye to Sony now.
The inexpensive Haoge EOS R to M adapter focus past infinity.
The first test shot I focused the top of the front building which was very close to infinity. Canon EOS R + Voigtlander 35mm f2 Ultron by earl dieta, on Flickr
Briefly met Scott to try out his CV 15mm v2 and as expected, heavy color shift on the corner.
Took a quick ISO3200 white wall shot to create a CornerFix and it removes most of the color shift. Not sure what's that on the top and bottom right corners, could be my finger when trying to focus. Canon EOS R + Voigtlander 15mm f4.5 II by earl dieta, on Flickr
The 15mm Heliar is behaving the same way as it always has.
Looks like CornerFix is the way to go. Haven't opened the program for the last few years, but it remains relevant for those with wide angle lenses. Thanks again for the samples!
Thank you very much Earl. It was great to meet you.
[BTW - The labeling above shows all as Canon EOS R + Voigtlander 35mm f2 Ultron by earl dieta, on Flickr, in error ]
The voightlander 15 v2 - based on the above and looking through the lcd - does not perform well on the R. I would characterize your first pictures before correction as modest, but the uncorrected 15 needed significant correction and still has a bit of green shift. So for me, I am sticking with the a7rii for packpacking for now and crossing my fingers for the R +mpx expected to be announced Feb 2020.
Thank you very much for your work and indulging my question - you have saved me from buying the R to test out the voight 15 v2.
You're welcome Scott, glad that it saved you the time and money from disappointment.
Hopefully the Pro R that will be announced next year will have BSI that can rectify the color shift issues.
I'm also curious to see now if the 24MP RP , like the A7, does not suffer these color issues compared to their higher MP brothers.
Thankfully for me, I only have 2 lenses to deal with and 35mm will be my main lens or the EF 40mm 2.8 so CornerFix is a solution I can deal with.
Thanks for noticing the incorrect description on the test photo, I'll fix it now.
EDIT: forgot to mention but I'm really impressed with the EVF and manual focusing capability of the R, I can focus wide open shots with regular EVF, don't always need to rely on magnify or focus peaking at times.
Still haven't found a way to configure the camera to exit focus magnify when half-pressing the shutter button though.
Is corner sharpness good with those lenses? I can't access those photos on Flickr to see for myself - it asks me to log in. I guess it's an account permissions thing?

I have uploaded them on dropbox for you to access and see what you think. https://www.dropbox.com/sh/2jton2b76gmfohz/AAC6Vyf4p91Q4RWeZIKrC1K-a?dl=0
for my need, they are sufficiently sharp.
The Loxia 21mm 2.8 was sharper than the CV 21mm 3.5 on any of my Sony cameras but it was also 2-3 times the size.
