I have been looking into purchasing a used Contax ( I'd love to get a new one but since the company went out of business no one seems to stock them) but I am not too familiar with the different models out there. The one that I have been focusing on has been the AX only because of the ability to use a variety of Zeiss lenses out there. I have always wanted to own Zeiss lenses, so I think Contax would be the way to go. Not to mention the prices on used bodies have dropped considerably. Can anyone comment on the durability of Contax SLR's? Are they as tough as Nikons? I have also been throwing around the idea of getting a Leica R5 or R6 instead. Used Leica's are pricier but I think that parts availability would be better than Contax if I needed a major repair. Any suggestions?
