Is it possible to convert a film slr camera to digital?

NO

Maybe, but it would probably be a lot cheaper to just buy the digital.

I know if you get your film developed at a place, anywhere they develop pictures, pharmacy's ect, they can put it on a disc for you for your computer, I guess that makes them digital!! Good luck!

Several years ago, someone had a plan to come out with "digital film." You would put it in the film chamber of an SLR and it had an image sensor that lined up with the shutter and it stored the images in flash memory where the film cannister would sit. Batteries resided where the take-up spool was. They advertised it very heavily in camera magazines, but it never came to fruition. I don't think it ever worked the way they thought it would.

I'm sure you could still convert a film camera to digital with some jerry-rigged set-up, but I can't imagine it being worth the hassle, unless you just want to be able to claim that you did it.

The simple answer for many makes of cameras is, No. I take it that you want to be able to switch from film to digital. Hassleblad cameras will take digital backs, and Leica (DMR) has developed a digital back for their R8 & R9 range, and you can get digital back for Mamiya 645, but they are very expensive (around $5000 for the DMR alone).
But if you're just thinking of moving to digital only, and you have a set of AF lenses you wished you could use with your new digital camera, consider buying one that is the same brand. If you have a Konica/Minolta SLR, you are in the happy position of being able to use you AF lenses with the Sony A100 and still use the anti-shake facility.

It is called a film scanner, unless your talking Hasselblad. Phase One makes a digital back for it for a few grand.

simple answer would have to be no.
use 2 slr film and have a couple of digi's as well, get the best of both worlds.
a digi will never (or at least for a while yet) be able to fully match the quality of film.

footnote: too many people buying a digi slr and setting themselves up as 'photographers', the results are usually terrible.

I have never heard of it being possible except with cameras able to change their backs.
I have a Canon SLR film camera that I had brought 2 extra auto focus lenses for, this is now worth probably less than 拢25 if I sold it so I have kept it and purchased a Canon 350D digital SLR that is compatible with my lenses. This unfortunately is a fact of life if you want to move forward and keep up to date with technology.
