посадил на сони Ю12 и фойхт попробовал на белой стенке потом на Никон. Для всех при обработке ткнул пипеткой в центр кадра чтоб скомпенсировать освещение
На обоих камерах есть колоршифт, и не слабый
Фильтры дают о себе знать. Здесь небольшое исследование. Старшие последние камеры в линейках БЗК ведут себя с дальномерными шириками лучше ,чем их ранние модели
It really depends on a particular lens and camera body combination. I can only say that the EOS R5 is a lot better than the EOS R was which had a lot of smearing magenta shift towards the edges, seems to be fixed now.
The performance ranking generally goes something like this in the order of sensor stack thickness plus micro lens optimisation, AA filter, etc.:
Leica M10-R 0.9mm (UV and IR filtration layers have been merged together, so even better than past M cameras)
Leica SL2 1.2mm (same improvements as above)
Nikon Z 1.1mm
Canon R5/R6 (newer) 1.25mm
Sigma fp 1.3mm
Panasonic S 1.45mm
Canon R/RP (older) 1.6mm
Sony 2.0mm (although with the BSI sensors performance has been improved, I also found the original A7S to be the better than the rest so A7SIII might work well)
The degradation is most severe with 35mm or wider, still present on 50mm, while my 75mm f/1.4 functioned perfectly with basically everything. For some reason, lenses without an aspheric element seem to perform a bit better. Symmetrical designs like Biogon are the most problematic.
You can find a lot of adapted rangefinder tests with Sony bodies on phillipreeve.net and a few threads here as well:
