Arthur T Knackerbracket has found the following story:
The unarguable benefits of digital photography has rendered the analog SLR obsolete for most purposes. This means that a wide selection of cameras and lenses are available on the second hand market for pennies on the dollar, making them ripe targets for hacking. [drtonis] decided to experiment with a quick and easy digital conversion to an old Canon A-1, and it’s got us excited about the possibilities.
It’s a simple hack, but a fun one. The SLR is opened up, and the spring plate for holding the film is removed. A Raspberry Pi camera then has its original lens removed, and is placed inside the film compartment. It’s held in with electrical tape, upon a 3mm shim to space it correctly to work with the original optics.

Same with Pentax. Unlike some of the other SLR makers, Pentax went out of their way to make their DSLRs compatible with their older K-mount film lenses, probably because they did not have the resources (as Canon and Nikon did) to introduce a full range of digital lenses all at once at the time. You can meter and use focus assist with the old lenses and the anti-shake works because it is in the camera, not in the lenses.
Nikon are the next best with supporting their older lenses, and Canon are the worst. Canon pissed off their users anyway back in the film days (late 80's) by changing their lens mounts, and today they go out of their way to make their APS format lenses unmountable on their 135 (or digital "Full-Frame") bodies, denying the user the option of cropping in post-processing.
I might be wrong, but I don't think any of the other 35mm camera makers made any attempt to allow their older lenses to be used on their digital cameras, if they made them at all.
