best super wideangle lens for cropped sensors, much better than tamron\tokina, has HSM suitable for Nikon D40\40X\60, great usability, nice EX look (as for me =)reviewed January 23rd, 2009 (purchased for $430)
not expected this wideangle lens to be so sharp

must have lens for cropped sensorreviewed January 23rd, 2009 (purchased for $360)
excellent resolution starting from f1.4
have got a moire over the hair with portrait shots on f1.4 - f2.0 (resolution of lens outperformed resolution of camera), in f4.0..f11.0 as sharp as blade, very nice bokeh rendition - soft and sweet, nothing like classical 50\1.8 "gears" and "circles"
great cobination of focal range and aperture - fully replaced even my very first kit lens, great for portrait shots, has a little barrel distorsion negligible for real shots and easy to fix if neccessary
p.s. a lot of people speaking about sigma quality variation, my own is 1st sample with no extra choice
recommend a lot!
