M10M screen looks the same - not flush.
I have no problem with 40+ MP on my Sony with slow shutter speeds. Granted IBIS helps a ton, but I’ve not had a real issue with the M10M either. Sure, there can be some blur in some shots with slow shutter speeds handheld, but how sharp were my shots on Tri-X at 1/15s? And that’s ignoring all the shots where I didn’t hold still enough. In my opinion, the ability to get sharp shots with these digital cameras is a non-issue. Take a burst of photos and choose the sharp one. Bump the ISO up a notch. Shoot like you always did and don’t worry about it. With the M10M, the sensor soldiers on even when I literally can’t focus with the RF patch.
I’ve also not had a real issue with focus accuracy of the RF. Well, yes I have, with 2 lenses. Leica 90/2 and a Konica 90/2.8. I did not have issues with them with film though I never shot with either of them much. The Leica 90 can be hard to see when it’s in focus wide open. The patch looks accurate, but there’s just enough wiggle room either way that I can be off a tiny bit. Live view helps, or maybe a magnifier. I wouldn’t be surprised if the low resolution of Tri-X masked this issue completely. The Konica is mega off and probably needs to be adjusted. However no real issues wide open with the 50/1.4 ASPH, ZM Sonnar, or even the 135/3.4.
You can always downsize images to 24 MP if you want.
