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.

It is not my primary lens, and that is why it only got a 4star (my favourite lenses are always shorter - 50mm for example) but it still great glass. It does get a little heavy for continuous shooting, especially with the heavier camera bodies, but is perfect to shoot people with from a distance at...

Consistent Output; Durable; Easily Interchangeable; Easy to get the hang of; Nice Bokeh; Strong Construction

Challenge to spot subject; Heavy

Great Lens would love a more expensive one f2 is usm ..but this is great very good lens for the money

The Canon 70-300mm f/4-5.6 L IS is a wonderful lens. It's made mostly of alloy; even its filter threads are metal.

Purchased 70-300L for use on my 7D for daylight field sports, and most importantly, to carry while when traveling. Processed (in Lightroom & NIK Suite) images from the 7D + 70-300L compare very favorably with those from my 5D MkII + 70-200L MkII.

Compact; Light weight; Fast auto focus (with both full and panning modes); Full time manual focus; Very sharp images; Responds well to micro focus adjustment

Cost, but then again it has 'L' build quality and performance; Lens collar is both expensive and (currently) unavailable

A fantastic lens. Everything you would expect from a L series lens. I have now taken around 3,000 photos using this lens on a 500D, mainly of kids playing sport. The focal length range is ideal. The build quality is great, it is as good today as when it came out of the box. Solid construction.

Easy to use; Build quality

At ￡432 the Canon EF 70-300mm f/4-5.6 IS USM lens should come with a lens hood, but it doesn't. However, it does come with a soft case to protect against scuffs and scrapes and features an Ultra-low dispersion (UD) element and Super Spectra coatings to help reduce fringeing, ghosting and flare.

I've used the product to photograph landscape and some wildlife. The Canon 70-300L works very well on both my Canon 5D2 and my Canon 50D. the only problem is that you can't zoom with the lens shade reversed.

Quaility product; Fast focusing

Too expensive; Heavy

Canon's incredibly popular compact, long-range shooter has finally received the L treatment it always deserved with the recent release of the Canon EF 70-300mm f/4-5.6L IS USM Telephoto ($1,570) .

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

Ultra-reliable AF and IS systems

Poorer sharpness past f/16
