For several years I've been travelling with two Zeiss Ikon Contax RF (post-war) bodies and four lenses. Just because a Leica would be too expensive for me.
Here in Europe, a Leica M costs three to four times as much as a Contax RF 😵. And even Nikon rangefinders are twice as expensive.
These old Contaxes are fully-mechanical, light-weight, versatile with good Zeiss lenses: beautiful working cameras.
- Make sure to find a working Contax. It's easy to check out a body: Does the shutter work (does it open at fast times also)? Does the rangefinder work properly? I found my bodies pretty quick. Two of them have been CLA'd, the third one is going to be. So far, it works even now.
- There are not too many technicians who know to work on a Contax body - but there are some of them.
- I'd recommend the post-war cameras IIa and IIIa because the pre-war shutters of Contax II/III were much louder. My Contax IIa and IIIa shutters are less loud than a friend's Leica M2 😛. I do have a 1936 Contax II also (see my avatar pic) and I love it, but it's very very loud.
- The Contax IIIa has a built-in light meter (like the pre-war III) but with a Selenium cell. Mine still works, but normally I use a Gossen Lunasix F or a Spot-Master light meter, with good results.
- Find a ever-ready case for any post-war Contax to carry it around. As Henry Scherer wrote on his site, the body's own strap locks are too weak to use.
- You will enjoy to use the Zeiss Sonnars 50, 85, and 135 mm. Similar to Contax bodies, those Zeiss lenses are much cheaper than Leitz / Leica lenses. The 50 mm f/1.5 Sonnar is a legend. The 85 mm f/2 Sonnar is a beautiful portrait lens. Similar to Leitz lenses, there were coated and (older) uncoated lenses. Last year I started to enjoy uncoated lenses with their "romantic" characteristics in specific situations: so far I have found uncoated 50 mm f/2 and 135 mm f/4 Sonnars.
- On a post-war Contax, the Zeiss Jena Biogon 35 mm wide-angle lens cannot be used: it was constructed for the pre-war body which had got a bit more space in its mirror box. On post-war bodies, only post-war "Zeiss-Opton" and "Carl Zeiss" Biogons can be used.
- Sure, compared to a Leica M, the Contax's viewfinder itself is its weak point. It was the Leica M who kicked the Contax off the market in the mid-50s. I use an additional Zeiss Ikon universal finder (which looks like a revolver) and it works fine for me. Especially because it enlarges the viewfinder image with telephoto lenses 😎.
