This is my first telephoto and my first L lens. The main purpose of this lens is just to take pictures of my kids and landscape. All I have to say is that all the positive comments about this lens you read is true.

ola, simplesmente fantastica...e minha lente favorita,eu adoro essa lente resolução de imagem impecavel ela e tudo oque se espera de uma lente L da canon...estou apaixonado por essa lente.

It is very good lens, images are very sharp and quality are superb! I would reccomend it.

Easy To Use; Fast Shutter Speed

Not Good In Low Light

Clean mean images with this superbly built lens.

Great ergonomics; top IS

f4 might be a tad slower to someone used to f2.8

Canon users were always gifted with a broad range of excellent tele lenses, especially zooms. At the time the Canon EF 70-200mm f/4 USM L hit the market back in 1999 it was another milestone but there was one itch left: wouldn't it be nice to have this lens with an image stabilizer ?

"This is a fast, quiet focusing lens with ""tack sharp"" quality. This is my first L series lens and the images it produces have more than exceeded my expectations. I would hightly recommend this lens."

This compact telephoto lens comes with an Image Stabilizer that compensates for camera shake so you can shoot at up to 4 shutter speed steps slower without blur.

This is my first L, but I got chance to try with other L lenses including 100-400. But so far this is one of the sharper L lenses. Comparing it with Canon 50 f/1.4, Rokinon 85 f/1.4(boken king), Canon 100mm f/2.8 macro(non-IS) and others for sharpness on 40D, nothing can beat my 50mm f/1.4.

My first L lens and is sharp; I had it exchanged once and the second is really good; Focal length is right for walk around to parks and play grounds in sunlight; I already knew its slower aperture and lack of IS and no complains on that; Good bokeh on longer side

My first copy was not good at f/4, but 1-stopped down, its is razor sharp but I returned for an exchange and got a fantastic(may be it is how it is) lens; No cons for me so far

I bought this lens for a safari holiday based on these reviews. They are right - it is a fantastic lens. It is relatively light and well balanced on my 7D and I can walk around all day with the camera in my hand. It is tack sharp at all focal lengths, excellent contrast and colour.

Superbly sharp; relatively light; useful range; superb IS
