Hello all. First of all, I'd like to say that I'm a Professional photographer but I don't have all the secrets and the TRUTH about photography. I think that every photographer has its prefered gear, prefered style and prefered brand. I will try to make this review as useful as possible and will give you input on how this lens performs "in real life" instead of only on checkboards and targets. My gear is a Nikon D7000 and I bought this lens 2 weeks ago after reading pretty good reviews ...

Have to say that I was a bit apprehensive buying Sigma having been a Canon Snob for years and having had trouble with some older Sigmas on Canon bodies (Err 99, OS still operating even when switched off etc etc.) I now have 3 Sigmas, EX10-20 3.5, EX70-200 2.8 OS and the 17-70 2.8-4 Contemporary lens and am blown away by the IQ of all three, Sigma have done a wonderful job with their lenses over recent years and now I'm a Sigma convert - absolutely nothing wrong with Canon glass - I have used ...

I just got this lens so this is an early set of impressions... Note this is the Sony Version so there is no OS on lens. Pros: (1) I like the look.

Having previously owned an original 17-70mm, I can safely say that this one is much better in every category plus a bit brighter at the long ...

Sigma have done a commendable job on this lens. I am using it with my D5200. It is very consistent throughout the focal length and aperture range, i.e. good results wide open to f16 at all angles. Center sharpness is excellent with a little fall off towards the corners, which are still mostly good to very good except at the wide end where there is a more noticeable decline (from 17-35mm). Still better than all wide-angle zooms I have tried at that angle though. The shorter zoom range compared ...

I have been very pleased with the performance of this lens.  I've put it through paces with indoor and outdoor use and the images are sharp and crisp. So far, no problems and I'm quite pleased with the quality of images produced with my 7D and the lens.
