I bought this lens as an addition to my 17-40 lens, using it on a Canon 7D I've had to learn to be very careful on what shutter speeds are used to avoid camera shake, even using a tripod. You need to have a very fast shutter speed to remove any hint of camera shake.

We take a closer look at the Canon EF 70-200mm f/4L IS USM and see if it can compete with its f/2.8 sibling

When comparing the f/4 variety of this lens to the flagship f/2.8L version, in some ways this Canon f/4 lens is better designed. This is thanks to the zoom ring being slightly wider and easier to use as it has a slightly smaller diameter.

I use this for outdoor sports and love the image quality and the ease of use. I upgraded from the non IS to the IS some time ago and IQ is just as good.

Great build and image quality, especially sharpness and contrast; Light enough to carry around and hand-hold

None I can think of practically

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.

The Canon EF 70-200mm f4L IS usm lens, is without doubt, one of the best lenses available. The results obtained from this lens, surpass any that I have had from any other Canon zoom lens. ( I have been using cheaper,non L series Canon lenses for over 25 years.

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. The lens optical system uses one fluorite lens element and two UD lens elements to render high-resolution, high-contrast image quality at...

"Optically speaking this lens is second to none! However even while it is claimed to be of professional quality I have to disagree: It seems that the mechanical parts are not better than any cheap consumer grade lens. I happened to bang this lens against the railing on a ship while turning around.
