Hi

Has anyone got the canon 20mm prime lens???

Im thinking of getting it as an addition to my 24-105mm for landscape use...

Anyone any advice or reviews of this lens.

On another thread people keep telling me to get the 17-40mm which I am seriously considering... however a bit of me wants the simplicity of the prime for landscapes. Anyone any thoughts?

That site trashes the Sigma 20mm f1.8 which I think is a great lens. They say they it vignettes more than they've ever seen but I've just checked some shots and vignetting is completely absent. Weird.

I can appreciate it is quite late now. Perhaps you may wish to give that a second go:

"Sigma 20mm f/1.8 EX DG Lens turned in some of the strongest vignetting I've seen - 5 stops in the full frame corners at f/1.8. The not-so-funny thing is, the Canon 20mm Lens turned in similar results at f/2.8 and remains over a full f-stop behind the Sigma in vignetting performance as it is stopped down. Full frame users will want to stop this lens down to at least f/4 or f/5.6 to get more even results. Users of 1.6x FOVCF bodies will likely not notice much vignetting." - http://www.the-digital-picture.com/Reviews/Sigma-20mm-F-1.8-EX-DG-Lens-Review.aspx

That would explain why you don't see that much of a problem, but you don't see a true 20mm either.
 
Ah...

In my defence I was doing other things at the time...and as I'm male I don't really multi task!! :nono::nuts:

I've just done some test shots and the Siggy 20mm looks ok to me at f1.8 (on APS-C, on which it's a great lens IMVHO.)
