You can do this with some 3rd party zooms designed for APS-C, e.g. the Tokina 11-16 f/2.8 has acceptable vignetting on FF at 16mm and works as a 14-16 on APS-H, but I think for primes you're out of luck.

I have used this on a 7D. Very sharp lens. I found the AF to be hit and miss, especially in lower light. When it is on - wow, super sharp - or if you manually focus.

It is easy to miss shots due to missed AF.
