I do not have a digital camera yet, but if I get one I want to use my Contarex lenses. None of the models (such as NEX and Olympus) appeal to me (adapters are made for Contarex lenses for them). The question is: If I get a Canon digital SLR body, are there particular models that have mounts that are not plastic, can be removed fairly easily, etc. A Rebel XT is available to me for modifying; is that as good a choice in that regard as any of the newer ones? This will be a machining job, and obviously I will be limited to using lenses without autofocus, so I need a camera body that will accomodate manual focus and f/stop/exposure settings. FYI: the lens register on my lenses is 46mm, and the Canon body register is 44mm. Plus, of course, the body must be modified to accept the unusual Contarex lens mount. Thank you for your suggestions.
