Is it just the 35mm or do other lenses faster than 2.8 vignette on FF?
The problem is limited to wide angle lenses, and has nothing to do with aperture as such. However, stopping down reduces vignetting when it is present.
Further: It is important to realize that those lenses who vignette on Full Frame sensors also vignette when used on a film body. My EF 20mm 2.8 USM shows severe vignetting both on the FF digital sensor of an 1Ds II and film when I use the EOS 5 film body. The Zeiss Distagon 21mm 2.8 shows very little vignetting on both. If Zeiss can make a good wide angle, Canon can if they truly set their minds to it.
The Zeiss example demonstrates that it is not the sensor size (or film size for that matter) in itself that is at fault. Therefore, the solution to the vignetting is to make better optics - and this has always been the case.

Quite true and I hope no one took my comments as a slight on the 5D. The reality is that we buy into a system and that system is only as good as its weakest components. If we have a great FF body it shouldn't be saddled with lenses that don't allow it to fulfill its potential. Yes, we can buy Zeiss optics but doing so eliminates the value of Canon's excellent AF system nad that is a big time loss for many. Sure we can deal with it but as long as we do Canon has no vested interest (loss of income) in correcting a major system flaw.
