These days most of my photography is done with an Olympus Stylus Epic or a Rollei 35. I don't want to become a classic camera collector as I'm afraid it would become another expensive addiction but I am intrigued by the functionality, build and general esthetic appeal of small mechanical cameras. I am especially attracted to the Leica IIIc/f and the Contax IIa for the above stated qualities as well as their compactness. It seems that either would make a good traveling or carry-anywhere camera. I would like to get some knowledge of the pros and cons of these two cameras and other factors that might help me choose one over the other. BTW, I am aware of the squinty viewfinders of these cameras and I would probably fit the appropriate C/V viewfinder.
