By reading the other reviews I believe I got an exceptionally good one. No problems with auto focus (unless I try to get to close to the subject) and I do not miss the IS at all even at full zoom hand held all my pictures come out just beautiful ! The only issue I have found is in high contrast you do get a lot of CA even with a CPL filter, but this is my only complaint. For the price you pay you get a really great lens.

Great lens for the price.
This lens is great for the price. I read a lot of reviews of people complaining that there is no IS on it. First of all you don't use an IS with a tripod. Secondly, using AF really doesn't give you the sharpest photos. That is what manual focal ring is for. Over all the lens MTP chart has a high rating at 75-200mm. If you want to have a good telephoto lens for a great price then this is a good buy. If you can't afford a more expensive lens and worry about possible camera shake, because there is no IS on this lens, remember you can always use mirror lock up on your camera or live view.

Good beginner lens, nothing special.
Great lens for beginners because of its low price. It's also fairly light for its focal length. It can produce a few nice photos provided you know what you're doing. But that's about where the pros end.
If you're looking for super-sharp professional quality images, you're going to have to look somewhere else.
The focus is soft to begin with, but once you go over 200mm it gets dramatically worse.
The Auto Focus has a lot of trouble with low-light situations, and is fairly picky while in AI Servo. Not to mention slow. I've had a couple instances where it took nearly 10 (ten) seconds to focus.
There's also an issue with Chromatic Aberration. Everyone loves pincushioning and purple fraying around their subject, right?
Anyway, aside from the soft focus, slow AF, and CA problems, the lack of the Image Stabilizer is truly the major downfall to this lens. I recommend using a tripod above 135mm, and I don't even attempt hand-shooting over 200mm after dozens of failed shots.
For a superior quality lens with a similar focal length that doesn't break your bank, I recommend picking up the 55-250mm IS II instead.

Infinity focus is blurry
Purchased December 2012 with bundled T3i.
Nice lens with wide zoom range.
Manual focus at the infinity setting is blurry, you have to back it off just a tad. Internal focusing mechanism just not up to old standards. You can not just set it to infinity and shoot.
Many posts on web about the out of focus at infinity issue. It is a problem I did not expect to have. Not critical but really annoying.
