Summary: Great les. It's not n Nikon lens, but then again, your not paying TRIPLE the price. The optics are clear and sharp, the AF works well and at 3.5 you can get effective depth of field in certain situation. Great purchase!
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..
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.
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.
Summary: I just don't get this lens. About 20% of the photos are great, without changing scene or settings. Also, when I purchased this, there was a rebate available from Tamron. I sent in the required form, serial number, etc.
