See examples Conclusions: The Canon EF 70-300mm f/4.5-5.6 DO IS USM is a compact, very fast-focusing zoom telephoto lens that provides generally excellent imaging function including excellent image stabilization at a high price. It is a weak performer at 300mm.

With the introduction of the Canon EF 70-300mm f/4-5.6 IS USM Lens, Canon has replaced one of its most popular lenses and its first image stabilized lens - the Canon EF 75-300mm f/4-5.6 IS .

This is a good quality product that offers good value for money in the very short term. Although as with most products of this type, the value will deteriorate over time and should be able to get a cheaper version next year. It's a great device with plenty of features that I would highly recommend.

If you're on a 1.3x or 1.6x crop body (the XTi for example) will give you 112-480mm, which is nice for the extra distance, however, if your wanting to be up with your family and friends and get full body shots you have to be standing quite far away.

Louder auto focus than other USM lenses, not by a lot though; Autofocus hunts in lowlight at 300mm

The Canon EF 70-300mm f/4-5.6 IS USM was introduced in October 2005 to replaced the old Canon 75-300mm f/4-5.6 IS USM . Although superficially, this lens looks very similar to the 75-300mm that it replaced, optically and functionally, this is a totally new lens, completely surpasses the old lens...

Yes, I would recommend this to a friend

Consistent Output; Durable; Easily Interchangeable; Lightweight; Sharp Focus

Overall, I rate this lens very high. It is truly a superb lens. The zoom range covers a broad spectrum of abilities. The sharpness is incredible. The cost is very high, but you are playing for a name brand lens. Well worth the money spent!

The clarity; the small size; lightweight

The price

This long, Tele stabilized zoom replaces Canon's popular 75-300mm f/4-5.6 full-frame IS lens, the industry's first IS/VR lens, introduced in 1995. The new model delivers better image stabilization (to three stops instead of two) and a wider zoom range.

I have used this lense often awsome flower or butterfly shots with crisp clear results great distance shots on deer ducks geese and all around great lense only complaint from me a tad bit heavy on front end.

Canon EF 70-300mm f/4-5.6 IS USM replaces an earlier generation EF 75-300mm f/4-5.6 IS USM model that was discontinued in mid 1990s.
