I am very interested in the Alpa upcoming Contax Shift mount for 12FPS. Would like to know how big the IC for Contax 45-90 and also 35mm. Does anyone has any experince or specification of these 645 lens? I am going to pair the lens with 44x33 CMOS sensor back.
In regards to IQ, how does the 45-90mm and 35mm perform at the corner? Thanks in advance.
