This review is from: Sigma 10-20mm f4-5.6 EX DC HSM - Canon fit lens (Camera)
First up let me say that I am not a professional photographer or even a very experienced amateur. I might not know all there is to know about photography but what I do know is that I LOVE what comes through this lens.
I was pleased with the build quality (as I have been with all my Sigma EX series lenses) and initial testing showed the autofocus to be fast, accurate and VERY quiet. This might not be surprising to those of you with a bag full of Canon L USM lenses but coming from consumer grade lenses this was a revelation.
I was seriously taken aback by just how wide 10mm is on a 1.6 crop camera (Such as Canons xxD and xxxD ranges). I could stand almost on top of subjects and still manage to get them all in. The extreme angles involved creates some distortion effects but these add to the pictures in my opinion.
The real joy however was when I returned from my first outing and began sorting through the pictures. The colours were fantastic, the images were, without exception, very sharp and the creative possibilities on a lens this wide made the photos stand out far more than the usual "snapshots" that a photographer of my calibre produces.
The ultra wide zoom made by Canon may well be better and I've no doubt that a full frame camera with professional grade lenses might yield better results but for this price I cannot find fault with Sigma's offering.
