Is it possible to convert a film SLR to digital?

Question

This may well be a question to which the answer is "can't be done," but I was wondering whether it was possible to convert a film SLR to a DSLR by putting a sensor in place of the film. I have a bunch of old bodies and lenses which I would love to be able to use, but I just don't want to mess around with film, so I was wondering whether it's possible to convert them to take digital images.

Answer

This has certainly been done with medium format SLRs that have interchangeable backs (e.g., Leaf and Phase One backs).

For a 35mm camera, the situation isn't nearly so positive. There was once a company that claimed to be working on a digital sensor that would be shaped like a 35mm film cannister with the sensor sticking out roughly like the film tongue. I'm reasonably certain they never produced even a partially working prototype, and even more certain they never put a product onto the market. Personally, I rather doubt it could be done.

In any case, the market opportunity for such a product is mostly past -- the vast majority of people who want to shoot digital have given up on the idea and bought digital bodies. Most have upgraded at least once by now, so used digital bodies are fairly common and quite reasonably priced...
