>>4384699Don't do this with sony, they have an overly thick IR filter that causes color shifts and sharpness loss with wide angle M mount lenses due to the excessively steep angle the light hits the sensor at.
It's so much leica uses special microlenses to control the problem. If you want leica-like results, Nikon Z cameras put a thinner filter stack on their sony sensors so the results are indistinguishable from leica's own sony sensors. They also have autofocus and adapters, and a 6 bit MtZ adapter that enables trap focus with M mount on the ZF. Even the cheapest nikon would be better for M mount lenses than a sony, a canon, a panasonic (also too thick), or a crop sensor (lmao cropping out all the sovl, imagine only using 1/2 or 1/4 of the lens you paid for)
