Excerpt: The reviews on this lens were not good 2 years ago as was the case with the 18 -135 also.It think it is asking to much of a lens to expect much in performance with such a wide range of barrel lengths.
Excerpt: I do mainly sports with long Canon zooms. I needed an inexpensive walk around lens that was smaller, lighter and would't knock things down in tight places. It's not quite a good as the more expensive Canon mid zooms, but does a great job for the price.
Pros: 70-200 28 Is Zoom, Durable, Easily Interchangeable, Id Mk Iv, Lightweight
Excerpt: I use this lens, as an amateur (if even that), instead of the 18-55 kit lens that came with my beginner Rebel T3. The lens creep is a given due to its weight, but the problem is easily solved with a thin rubber band. It is typical Canon quality.
Excerpt: It is a nice lens and it is versatile. The only downside of it for now, it expand by itself when the camera is in a face down position like when I use my BlackRapid strap. I contacted Canon and they said me it is normal.
Excerpt: I really like this lens. I use it almost daily for a huge variety of shoots. From close up nature photography to portraits I do it all with this lens. I would love to 'love' this lens. However, it is quite heavy and through use the lens creep is atrocious.
Pros: Consistent Output, Durable, Fast / accurate auto-focus
Excerpt: The lens doesn't seem to do well in low light. When the lens is pointed down, it has insuffient friction to maintain the zoom. So if you point it down, it zooms out fully. I find this highly irritating. In good light, it performs well throughout its length.
