I no longer shoot DX but, when I did I loved this lens. Some pretty strong distortion at and near 10mm which is not unusual and easily corrected in PP. However, you might look at Thom Hogan's appraisal of it and also look at the Sigma 10-20 (which Thom likes), or, even the newer 8-16. Both are a lot cheaper and get very good marks. Some very experienced shooters here like both Sigma's. Either would complement your very fine 16-85 nicely. I have the 16-35 which is excellent, but, not all that wide on DX.
