super wide angle glass for FF

[crazyjackphoto]

hello,

Just wanted to ask for some opinion before I actually go try out. Looking for a wide angle zoom lens. prefer with fixed f stop. Is going on full frame & don't really want too much distortion. Mostly going to be for landscapes. any suggestions? canon, sigma, tamron & tokina. Thanks a lot

I have the 17-40 f/4L and I have used it on my step-dad's 5D. I did not notice any distortion, but there was noticeable vignetting at 17mm. The 16-35 MkII gets great reviews for its edge to edge sharpness, but I have not tried it.

Unless you had thick filters or the wrong hood...there should be no vignetting. There will be some light fall off near the corners of any wide angle lens, which is probably what you were seeing.

If you want to get wide with your 5D, I recommand the sigma 12-24mm, that's the wider lens you can get on non-fisheyes lens
This + a 24-70 f2.8L or the 17-40 f4L would work nice
