OKIE DOKIE --- Like I said, Optical Light Path Physics is not exactly my strong point, but what I AM CURIOUS ABOUT...is it or is it not true that the Canon 7D Mk2 contains a sensor that allows for a focal plane distance of anywhere from 25 to 44 mm if an adapter was able to be used?
I simply don't know how it could be done BUT I do wonder based upon YOUR professional medical/optical experience and opinion .... if it is at all possible (beyond any Canon financial or product lineup issues!) to create a box-like camera as thin as 27 mm with a lens bump containing what I am assuming an EF-S mount allowing for an APS-C sensor size to actually work in a mirrorless configuration.
CAN IT BE DONE?
What are the light path physics behind your yes or no answer?
