Hi there, my first post so please bear with me. I've been a Canon slr user for many years (1975) and currently have a 7dmk2 but I want to buy a 6dmk2 as an additional body. Like many people of my age I've hundreds of slides which I want to digitize and so I tried out my old slide copier (basically a 6 inch tube with a small lens in it) on the 7d with quite good results but obviously cropped. My question is has anyone used a full frame camera to copy 35mm slides and what results did you get? Thanks in advance.
