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: I remember using this lens back in the film days. It worked well, but now with digital I like the images more. I am using it on a Canon 6D and since it is full frame, it is very particular about the quality of the lens. Edges and vignetting are not too bad depending on how you use it.
Pros: Fast / accurate auto-focus, Great zoom range, Lightweight
Cons: Edges Slightly Soft, F56 A Little Slow, Lens Creep
