I am looking to get an Ultra Wide Angle lens for my Nikon D200. I have kind of narrowed it down to the Sigma 10-20 f4-5.6 or the Tamron SP AF10-24mm Di II. The reviews for both seem to be good and theres very little difference in the price. The Tamron I suppose has the edge with it 10-24 as against the Sigmas 10-20 but I was wondering if anyone out there as either or both and what are their opinions.
personally I shoot with the sigma and I have to say I rarely use it above 14-16mm so it would not bother me about the extra 4mm at the end that is less important as you probably have this covered by other lenses
