7 out of 10 points and not recommendedNice feel and handles well. Seems to focus fastbut then it doesn't need to focus much at 11mmNot very sharp around the edges especially at 11mm regardless of f/stop. Had I seen the tests I would have bought something else. OK lens but not pro quality unless you zoom to about 13mm and keep the f-stop between 8 and 11
Not sure if I am too picky or not but I have been disappointed with the results of this lens so far. I have to shoot at f/8 but no smaller than f/11 and it helps if you zoom closer than the widest setting of 11mm. Construction quality seems to be excellent and focus speed is adequate. It seems that people would buy this lens for the 11mm setting so Tamron should concentrate on making it sharp at 11mm. It is excellent at 18mm but I already own a Canon 16-35L/2.8 that is sharp there as well.reviewed February 24th, 2007 (purchased for $550)
had I seen these tests I wouldhave opted for the Sigma or Tokina versions but maybe I just got a les that just barely passed the tolerance tests.
