Digital Lens + Film Body = Vignetting + "Fish Eye"?

[doUbleCHIN]

I m just curious whether digital lens design for DSLR can be use for Film Body. Well, judging from the results, You can decide for yourself. I like some of them though but don't think will do it again. All kaput.

I expect to get Vignetting due to the "crop factor" of digital lens so I zoom in more with the hope that it will go away. I tried the max focal length of 50mm, it doesn't work. Anyone try before, can get rid of the black ring if we Zoom in more?

All with dynax 5 and Sigma 18-50mm EX DC.
