Zenit 11
It's in a mint condition and even though our market is oversaturated with Zenits, it's hard to find one with no chips or dents and with correctly functioning selenium light meter. So I hate it, but I'm keeping it.
Contax II
Whimsical shutter that has been repaired several times already, tiny-weeny viewfinder which makes me want to puke after glorious HD Window of Olympus OM-1. Why am I keeping it? It's Contax.
Nikon N80
It's too digital-like. Sometimes I think the only thing that makes it different from digital is the absence of display on the back. I keep it because it's convenient sometimes, when I need autofocus. It's my only AF film camera.
