    No, not really any reason :) The image quality would suffer, and a M4/3 lens need an active mount to be able to communicate with the camera, aperture, focus, IS, lens corrections all need electronic communication to work.

    Nope. You'd need to gut the mirror box out of the Canon to get close enough to the sensor/film plane to be in focus, otherwise any M4/3 lens you'd use would be in (extreme) macro mode.

    That was a much better explanation, thanks Dom. It's also possible one of the grub screws holding the focus ring have been replaced with a longer one and effectively locking the focus ring. So check them all just in case..

    I am not familiar with this particular lens, but if you look on the focus ring, do you find a grub screw? This may have been use to set and lock the focus distance. If you find one, just unscrew it slightly and move the focus ring, not holding the focus scale, as this may move, and you've now changed the placement of the focus distance markings instead. The 17-85/1:1.8 should be for 16mm cameras. Sure, it's possible to mount a tripod collar on the lens, but you'll have to find one or make one yourself. Depending on your camera, a base plate, rods and lens support is another way to rig it.

    I've got a pre-set Hidenon 28/2.8 with a T2-mount, so it does exist wide angle lenses in this mount :)

    Why not try some water based ink first, that is easily removed if it turns out that it doesn't work on your lens, i.e. it becomes visible. I think you can use anything from a permanent marker pen to Humbrol paint when you want it to be permanent; http://www.dpreview.com/forums/post/51560863

    You can use matte black paint and paint out the scratch. See here; http://photo.net/bboard/q-and-a-fetch-msg?topic_id=23&msg_id=0016zA and here http://photo.net/canon-eos-digital-camera-forum/00J4Zh

    1. This could be glue or something stuck on the lens. It's not easy to get a crack looking like that. 2. This could be cleaning residue, or it could be some light damage to the coating. I've got a Taylor-Hobson with quite a lot of damage to the coating, both front and rear lens. The rear lens look similar to this but much worse. I don't think it will affect the image in your case.
