The worlds best 70-300. This lens is amazing and will not let you down. Perfect for full frame or crop sensor Canon DSLRs. Great focal range for field sports such as rugby, soccer etc. The AF and stabilizer are awesome.

When we first saw the new Canon EF 70-300mm f/4-5.6 L IS USM lens, we thought it just looked like a standard 70-300mm lens with a white overcoat on. After using the lens for some time, we're blown away by the image clarity, sharpness, build quality and speed of focusing.

Canon users are spoilt for choice when it comes to lenses with a 70-300mm zoom range or similar. The full range of options is: the EF 70-300mm f/4-5.6L IS USM (SRP £1,600); EF 70-300mm f/4-5.6 IS USM (SRP £650); EF 75-300mm f/4-5.6 III USM (SRP £350); EF 75-300mm f/4-5.6 III (SRP £300); EF 70-300mm...

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

Great all around high quality L Series Canon lens. Excellent image quality from wide to higher zoom. Rapid, quiet, accurate focus. Comparatively lightweight and compact for quality of lens and wide zoom range.[...] I have several other L series lenses; this one is up to the high standards of Canon.

Relatively Lightweight; Superb optics; Wide zoom range

Excelente Lente ! Ótimo vendedor ! Já tirei umas 1000 fotos ! O Estabilizador em 2 níveis funciona muito bem quanto a lente toda aberta e uma ótima opção e a trava de zoom que permite a utilização da lento como uma 70mm fixa ! Recomendo para fotografar natureza e esportes de velocidade !

I returned mine and got a higher-quality older lens off of eBay. I'm very happy that I did. This lens isn't very sharp at all but will fit the bill if you just need a lens and aren't too picky about the image quality.
