the image stabiliser is the reason I bought the zoom for wildlife,works a treat...

When I purchased my 7D, I also picked this lens up for some wildlife and nature photography. With the cropped sensor, 300mm is close enough for animals that don't want to eat you... I'm impressed. Images are pretty sharp and colorful.

Canon announced the EF 70-300mm f/4-5.6L IS USM, on 26 August, 2010 in the lead-in to September's Photokina Trade Show. Targeted at professionals and advanced amateur photographers it's surprisingly compact for its specifications and usable with all of the company's DLSR cameras.

Handling and features Performance Verdict Specification Canon have given the 70-300mm range an L-series makeover and as a result this lens sports silent autofocus, with full-time manual override, weather sealing, optical stabilisation and tougher build quality than you might normally find on a lens...

Excellent build quality; Very good sharpness that is consistent through the range; Low CA; Low distortion; Effective optical stabilisation

May seem expensive for a f/4-5.6 zoom (although the premium is probably worth the extra in this case

A bit too expensive than its tamron counterpart but they differ in quality. Amazing picture quality is given by this lens. Perfect zoom and sharp and fast focus. A nice lens to buy.

I bought this lens years ago, but don't have the need to use it much. Reading reviews about poor focus at 300mm, I thought I would take a couple of shots. I shot this photo of a cedar fence at 20 ft at 300mm. I thought the IQ was very acceptable for this price lens.
