For an amazing telephoto zoom, with terrific image quality and amazing build quality, look no further than the all around performer that is the Canon 70-300L

Amazing build quality; Stunning image quality; Fast and accurate AF; Rock solid IS

Canon doesn't provide a tripod collar with the lens; you have to buy it after

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.

The image shown is of Canon -EF 70-300mm f/4-5.6L lens and not Canon -EF 70-300mm f/4-5.6 so don't be confused like i was when i received the lens.Its a bit heavy using a tripod would b good and the lens becomes useless in low-light. Over-all its a good lens for a beginner with a good zoom.

Canon's EF 70-300mm f4-5.6L IS USM brings L quality to this popular zoom range. You get tough build quality, quick and quiet USM autofocusing, full-time manual focusing, effective image stabilisation and great optical quality in a barrel that's comfortably shorter (albeit fatter and heavier) than...

It's just a joy to use, and very sharp. It's also a significant step up from the Tamron 70-300 VC, you'll have no worries shooting wide open at 300mm with this one! Perfect on APS-C. Also, do not underestimate how important portability is, it's very compact at 70mm.

Sharp throughout zoom range at f5.6, colour and contrast fantastic; Auto focus is amazingly fast, IS is superb; Very compact, not overly heavy; Metal filter threads; Zoom lock means hood can be stored in reverse orientation and still removed without zooming the lens out

None, well, maybe price; The relatively slow aperture and extension on zooming are not cons, in lens terms they are necessary design compromises to make it the size, weight and focal length range it is

Excellent image quality in a compact size. Image stabilization works very well. The downside is the F stop of 4-5.6 and the weight if you plan to...

Size and quality

F stop of 4-5.6

This is definitely a high quality lens, not as slow as it says on paper, image quality maintains high even at max zoom with lots of details. Unless you are shooting high speed events, I see no need for L lenses, this will work for me just fine, I mean, more than just fine!

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

I purchased this zoom lens from ZeeMo Digital at a very great price and it lived up to the expectations I envisioned.It was shipped out quickly and was also packaged nicely.

I was looking for a lens that could take shots of wildlife from a distance. This lens certainly fits the bill and the IS helps in low light. I was also looking at the 100-400mm lens but the negative comments about its barrel focusing system pushed me towards this one.

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Rugged; Strong Construction

Heavy; Poor in Low Light
