Will a full frame lens work on the af 100?

Just sold my HVX with Letus set up and now eying on the af 100. I still have all my Nikon and Canon full frame lenses and just wanted to know if I could transition their use into the af 100?

I figure this would be something obvious but just wanted to check.

BTW, I know there would be a cropping factor full frame to 4/3 but just wanted to know if there are any other factors.

thanks
 
You'll be using the center/sweet-spot of most lenses, so optically they should be just fine. Breathing, aperture control, focus repeatability, etc. will be issues, but ones you must already be familiar with.

Wouldn't that all depend on the lens? And wouldn't the lens be more prone to exhibiting diffraction?

Optically, if a lens can resolve for a full frame (5DII or D3x) still camera, I don't see how it would be limited by diffraction* unless stopped way down (say, past f/16 for a f/2.8 lens), just like on a pixel-dense still camera. As far as the variety of quality and mechanics, yes, of course it'll vary by lens, but a good example of a very good Canon lens that has a lot wrong with it when used for video, the 85mm f/1.2 L Mark I breathes noticeably, its aperture can't be controlled mechanically, and its focusing mechanism isn't mechanical (focus-by-wire), nor does it have hard stops (like most if not all Canon brand EF lenses, I believe); it also has serious CA issues, has a large filter size, focuses slowly, and is rather unwieldy, but that's kinda besides the point.

Actually, you're right. Diffraction wouldn't be any major issue until you're around the 11~16 area... CA would be perhaps.

The 85/1.2 is definitely a pretty still lens... but when things aren't still it's a different (and most heinous) ballgame.

Nice, somewhat simple article on diffraction: http://www.aguntherphotography.com/tutorial/diffraction-limits-of-resolution.html

I shot some stills and video (BTS modeling, so I wasn't trying to shoot tight shirt prints or bug screens) with my 5DII + 85/1.2/II yesterday, wide open. Buzzed focus left and right, but the few seconds here and there that are 'on', are beautiful.
