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.

Image stabilized; Superior build quality; Super-sharp images

Slow Auto-Focus

CANON EF 70-300mm f4-5.6L IS USM review. As a dedicated nature photographer much of my shooting is with wide angle lenses but I recently decided I wanted a telephoto zoom for wildlife, particularly birds. My criteria were: Min.

A well-built, pro-spec lens boasting excellent performance

Ultra-reliable AF and IS systems

Poorer sharpness past f/16

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.

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 because I do a bit of "birding" and I wanted a long lens. The non "L" version was a bit disappointing. This is substantially bulkier, and heavier but oh my, it is terrific!

Sharp as a tack; good fast focusing

Big; heavy; (compared to non L version
