My first real experience with a medium format was with a Yashica TLR.
Yeah, it's quite a bit different than the SLRs I'm used to, but I had a lot of fun with that borrowed camera.
The 330, as I understand, is a boat anchor to carry around, but I do like the idea of interchangeable lenses, and I've gotten more
positive comments on that 124 I used than on anything else (the canonet has gotten a bit of attention too, though).
