9 out of 10 points and recommendedgood built, decent macro, fast focussing, good sharpness, nice bokeh for this kind of lensa little heavy, corners soft at 17mm wide open, focus ring rotates while AF operation
Nice lens with a decent built quality. I don't understand, why the review here is so poor i guess they got a lemon.reviewed April 7th, 2010 (purchased for $480)
Also the macro comment is wrong, they write "just under 9 inches" This is measured from the sensor plane! This lens focusses as close as 1cm from the front element. With manual focus even closer.Closer is hardly possible.
