I'm new to APUG, so I'm going to resurrect this thread.
Besides my treasured Mamiaflex and C22, I have:
Pentax 645N and two 645 bodies
Kodak Medalist II
Polaroid 100A Land Camera
Box cameras: Two Argus Super 75s, a Brownie Hawkeye Flash, and an Imperial Mark XII (if that counts as a camera)
and for 135 film, I have a Pentax K2, several KXes, an MX, a Nikon F, and a few FMs
Then there's the "broken pile".... (and a couple Digital Camera Simulators)
I have done more with the Mamiaflex than with any of the others. I mostly use it to shoot landscapes with Ektar. The C22 would have had more use, but it took quite a while to get the winder issue worked out. Now it is good as gold, but I only have one good waist-level viewfinder - my Porroflex is desilvering in a few spots. I have an 80, 135, and 180mm for them, but that pile needs to grow. I'm looking for the legendary 55mm.
Since I got the Medalist II a few months ago, it has been my new favorite toy. I just wish there was a way I could stuff a 220 roll of Velvia 50 in there. I would love to see that strip of 6x9 in full color.
