Canon EF 70-300mm f4-5.6L IS USM

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...

For private use WOW!

Well I have tried the lens out today after getting receipt this morning. Not for professional use perhaps but with image stabilisation and compact size. Great for zooming in on subjects and even good with macro use. Does what I need for now.

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

Canon EF 70-300mm f/4.5-5.6 DO IS USM Review

The Canon EF 70-300mm f/4.5-5.6 DO IS USM ($1,399) is quite compact when you consider its zoom range and compatibility with full-frame cameras. Its DO designation refers to a design that incorporates diffractive optics, which helps keep the size down, but its image quality isn't up to snuff when compared with more traditional lens designs. If you're going to spend this much on a Canon telezoom, we recommend the EF 70-200mm f/4L IS USM ($1,199.00 at Amazon) ; its telephoto range isn't quite as long, but your images will be noticeably crisper. The 70-300mm ($1,099.95 at Amazon)  measures just 3.9 by 3.2 inches (HD) when set to the 70mm position, weighs 1.6 pounds, and supports 58mm front filters. It can focus to 4.6 feet, which is good enough for Canon to qualify it as a macro lens. But its maximum magnification is only 0.19x, just about one-fifth life size, so calling it a macro lens is a bit of a stretch, especially when you consider the distortion that it introduces to images wh...

The Canon EF 70-300mm f/4.5-5.6 DO IS USM is a very compact telezoom for full-frame Canon SLRs, but its image quality is lacking.

Compact; Optically stabilized; Full-frame coverage

Pricey; Not that sharp; Lots of distortion when zoomed
