This is my first post so please be kind.
I've promised myself a wee treat, along the lines of a classy film SLR and a 40mm-ish lens. There are quite a few combinations, in no particular order: OM2 and 40mm Zuiko, Pentax MX and 40mm M, Nikon FM3A or FM2 or F3 with the 40mm Voigtlander and a Contax of some description with the Tessar. I love Contax cameras and have had an original RTS and a 137MD in the past. I don't have any experience of the later models such as the RX. I know there's quite a difference in price between the outfits above but I'm not too bothered about price. I've got a budget of about £500-£600. Can anyone say how the the RX/Tessar combo might shape up against the others? Are there other Contaxes I should be considering?
I'd be using the camera for general shooting in towns and cities and as a walkabout outfit using black and white exclusively. I've never taken to Canon cameras which is why there's no Canon option.
