The issue you'll have with Cannon is that they use a different distance from the lens flange to the focal plane, so I believe you'll lose the infinity focus. That's why most lens adapters will allow you to take a pentax lens and put it on a canon, but not the other way around. Also check out linkdelight.com. I was there a few years ago and remember them having a wide selection of cheap lens mount adapters. Don't know if they have what you're looking for or not.
Good luck and happy shooting!
i think i'll give up on this. Decided to sell my zenitar and get pentax mount, thats the only better way. The adapter itself will cost about used zenitar's price. Im not going to use other canon lens, just the fisheye in my collection.
Btw, do u guys knw about Samyang performance?
