I do wonder if it\'s possible that the micro-lenses themselves at the borders/ edges of the sensor could be resulting in a focus difference with lenses that have extreme ray angles (such as this Biogon) in that area IF they are not optimized perfectly for the lens.
My bet is still the filter stack, not the micro lenses. They should only affect IQ on a pixel-to-pixel level.
Fully agreed. Also I would like to mention that all wides I have used, ZM 18, 25 and 35 have a very flat field, especially at infinity. The ZM 18 may benefit from stopping down slightly but not the 25 and 35. That is on the M9.
