Summary: Mediocre is the best way to describe this lens...it does everything ok...but nothing great. It's soft at f/3.5 and also at f/18+...it's best used in the middle around f/11. For a cheap lens it's acceptable, but don't be fooled by 4 or 5 star ratings...you shouldn't expect the same result that you will get with a high end lens.
Summary: The lens arrived in much better condition than what I expected. (It was rated "Good Condition".) No scratches on the lens, very clean, and operated as it should. Auto focus was a little tricky in lower light. Worked very well in full daylight. Maybe not the best lens for low light situations. Images were very good, but not the sharpest. For it's price range, this is a very good all purpose lens.
Excerpt: I have most used this lens for indoor and outdoor activities with groups of children and youth. It is very sharp, handles well, and excellent for use without a flash. So far I don't have anything I don't like about it.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh
They are great for the price BUT be sure you get the one in this photo

Summary: I have bought 5 of these and three where gifts. The one I got this time must have been some very early model or a different grey market lesser lens. Mine will not auto focus on any of my old Cannon film cameras or any of my digital Canon cameras. I own quite a few so it IS the lens and not my cameras. I can use it manually and with the price I paid I will not complain anymore.

Summary: for this low price good sharpness, but not extremely sharp, nice colors, high contrast, but some few CA's (must be eliminated with PHSh for bigger prints) with macro lens and f11 good macro shootings possible no distorsion remarkable on wide angle therefore 8 points
Excerpt: Build and design features are very good. Has a lens creep lock. Image quality in well lighted environments is good. Low light environments are problematic, it produces significant noise. Since I shoot news, I prefer candid shots and don't want to distract the people I'm photographing with a flash.I returned it because of the noise issue.
