I have had a Rolleicord IVB, a Yashica D, 3 Yashica 124, Richoflex, Ciroflex and Minolta Autocord. The reason for the variety of 124 Yashicas is that not all lenses are equal. I wanted to make big enlargements and found that a couple were not as sharp. I kept the best for myself and sold the rest. Unless yiu are really looking at super enlargements they should all be good. When I was doing weddings I always carried a spare camera and flash just in case. The Minolta was super sharp but I could not get used to the focusing on the bottom of the taking lens.
