Optical stabilization system; Fixed aperture through zoom range; Relatively light; Sharp images

Great for shooting my son's flag football games!

Awesome Low Light Lens; Consistent Output; Fast / accurate auto-focus; Strong Construction

Pros: Razor sharp focus. Fast lens. Cons: Haven't found any yet Other thoughts: This lens is one of the finest lenses I have used. The pictures are unbelievable. There really is a huge difference when choosing a Canon L lens. [...]

Its compact size and Light weight can be deceiving when put next to its bigger brother, But at its f4 aperture the performance of this lens is truly amazing the IS system works well Testing it i went as low as 1/13 shutter speed at 200mm with IS on and it kept on taking usable images ..

I mostly shoot landscape and nature and this is by far one of the best lenses I've owned. Even wide open it's amazingly sharp and focuses very fast. It will hunt a bit for focus in less than optimal light, but compared to the weight and cost of its 2.8 big brother this was by far the better option...

Fast / accurate auto-focus; Nice Bokeh; Rugged; Strong Construction

Heavy

You want a medium telephoto lens for your Canon dSLR, something with a constant aperture, solidly built with pro quality, yet light enough to carry on adventure to some faraway part of the world. You have looked at the f2.8 models but didn't think you could afford them or the Sherpa to carry them.
