Some of us in this Classic Camera Forum like to use and collect wonderful old cameras. A few display their collection in full glory and have become well known on this forum. Reading the Classic Camera Forum has been a pastime in itself. Establishing a theme is personal taste, but it is interesting to see what theme collectors have chosen. We know who has a serious Pentax LX collection - I had not realized the LX had so many viewfinder accessories. I have been collecting classic cameras and electronic film cameras for the past couple of years now, and revolving them back on the market as I retain a small set of favorites. The evolution of my revolving collection has been interesting, and I refer to a highly regarded Leica repair specialist as an online mentor for inquiries about internal quality and reliability. I favor the short telephoto range (85-135mm). Here are the characteristics that have settled, and every classic camera I own is mentioned below: 1. Fully operational 35mm cameras ready to take a picture. 2. Exceptional viewfinder performance. 3. Handling ergonomics: Highly subjective with each camera. 4. Buttery smooth lens focus action: C/Y lenses. 5. Fully mechanical chrome metal cameras without meter or battery: Nikon F, Canon P, Leica M3. 6. Intellectual study of history and variations of a basic model: Nikon F. 7. LTM and tiny lenses: Canon P. 8. Modern electronic film cameras: Nikon F4, Leica SL2 (meter only), Leica R8, Contax RTSII. I enjoy sampling, so Leica is not as much fun as other cameras. They are most elegant, but just too much a handful to fully explore. A key frustration with old cameras is a difficulty finding diopters, as I prefer close contact with the viewfinder in darkness than using glasses at a distance. I don't even think the Canon P was meant to use a diopter. Most of the electronic cameras in my collection have a built-in diopter. The Contax AX was not mentioned, as its thickness is odd to handle, but its amazing to fiddle with a classic era camera that converts a simple manual focus C/Y lens to an autofocus lens without external movement AND converts the same lens to a macro lens. Contax has engineering elegance - the RTSII has a battery cap cover just like the Nikon F back cover locking screw - no ugly coin slot. I cannot explain my love of the Nikon F4 in its full vertical configuration and fully loaded - it just feels right despite its weight. I wish the Nikon Df was modeled after the F4 instead of the F3. I also maintain an electronic journal of interesting information relating to the cameras and lenses of interest. Have you thought about your own classic camera collecting evolution? I posted my thoughts here in the hope that some of you can relate to some of my preferences and can suggest further development. I feel overwhelmed and drawn-out over a wide spectrum, so I really wish to focus on a selected few cameras, lenses, or themes. Any ideas on that would be welcomed as well.
