[Robin] is a hobby photographer with some very nice old film camera gear. But who has the money or patience for developing film these days? (Well, lots of people, especially artists, but that’s a different Hackaday article.) So to update his old gear without breaking the bank, he glommed a Sony Nex digital camera onto the back of a nice old Nikon, and documented the process for us.
A friend of mine once said, “never underestimate what a good engineer can do with a file and patience.” [Robin]’s hack essentially consists of grinding the Sony’s CMOS sensor to fit exactly where the film plane would be in the old Nikon. For him, this meant relocating the IR filter glass, because it wouldn’t fit with the shutter, and then slowly and accurately trimming down the edges of the CMOS sensor’s retaining frame until it was just right.
