The full 35mm are hevier and probably will give less vignetting, but ill give more light to the actual subject?
I actually use mostly Full Frame lenses on my T1i, I had them form my eos 1. And they perform quite well, once I got uses to the crop factor thing. I uses to use the 50mm prime allot on full frame and not to much a 28mm prime. But since moving to the T1i, I find myself using a 28mm prime way more. So I recently traded my ef 28mm 2.8 for a used ef 28mm 1.8 USM lens instead. And I am loving it.

If I went for a sigma 12-24mm wide angle that works on both FF and crop, I was told I would see the vignetting on the ff not the crop body at the wider end.
