EVF usage and its co-factors is one area where it seems fruitless to discuss the matter with your peers, because what your eyes see is (apparently) unlike what anyone else sees. If anyone was to scientifically look into the field, large individual variations would immediately become plain to see.
A related issue came to light reading about lenses with residual SA may not work well on camera focus confirmation systems like Nikon's Zf body.
'Has anyone else noticed that the Nikon Zf focus confirmation seems to be much more reliable with lenses that are well corrected for spherical aberration (SA)? When I adapt lenses with more residual SA, the green focus confirmation still works, but it doesn't seem to be as accurate or consistent.'
You can imagine this finding pushing manufacturers into promoting high levels of 'correction' as a prerequisite for MF focus accuracy. 'Use better lenses!', they can be expected to advise.
Yes,
The ZF is probably the best performer when it comes to this. No other camera, even the LS series will do the focus confirmation like nikon does.
However, I left it out of this conversation because it is not a rangefinder style camera but it's actually very similar in size to the ev1 and m11 except for the prism.
Well, actually Canon does focus confirmation at least as well as Nikon, and I actually don't have trouble with the Canon focus aids and my Canon R5 II with my Minolta 58 f/1.2, that has quite a bit of spherical aberration. When focus confirmation missed on the Canon is when it doesn't realize what I want to focus on but about 99 percent of the time it gets it right and eye AF has not missed for me yet.
