I wanted to continue my Contaflex collection up through the Icarex models, but have gotten sidetracked. They certainly are well crafted cameras.
The Contaflex Series was mechanically the best one, Zeiss/Ikon had back in it's day. The Icarex series was being considered an "Old men's camera", but i can't see why. Perhaps the brick-like design, perhaps because i am in my 40's...but i do like it.
I've finally managed to get the TM (M42, "ThreadMount") Icarex 35S Version way cheaply into great Condition, BM "BajonetMount" Versions are usually cheaper, and much more widespread. Yes, these SLRs are well crafted, some german review wrote about "An old's man Camera"...and afaik they're made out of Alu-Magnesium. They're heavy & robust.
I think the "old man's" moniker came about because at the time these cameras were introduced, only old men who had been Zeiss fans for a long time were buying them. They had already been surpassed technically by smaller cameras introduced from Japan.
ps: BTW, Lenslover, I don't see your photos, just an icon. How did you post them?
