Can use any of my very extensive system of OM lenses on my Canon with the adapter with chip. I use only very fast lenses, wide open or near wide open in low light situations, however, as the manual aperture is not conducive to use at small aperture settings. As a result of having some fast Canon zooms, the only OM lens I have a real reason to still use is the 135mm f/2.8 or the 24mm f/2. The 24mm PC lens does not have sufficient FOV on APS-C to warrant its use, which is the only real reason I have, even today, for wanting to get FF digital body.
If you ever get the itch to sell the 24PC, let me know...I'd be willing to give you a fair price for it (and hopefully, your definition of 'fair' and mine wouldn't be too far off
).
