I just got my 16-55mm lens today. Like everyone said the quality is no question about it. Its build to last, heavy but in a good way. I like the rubber on the zoom and the "clik" feeling on the aperture ring. Haven't had a chance to try it but once i try i will share it with you guys. I've done research before buying that lens, and decided to buy after that. Some minor chromatic aberration and distortion in some point of focal range but easily corrected.
