A compact telephoto zoom lens from Canon's 'L' series.

Excellent optical quality; Superb build quality; Very effective image stabilisation; Fast to focus; Sealed against weather and dust; Light weight

Sometime miss-focuses near minimum focus distance

Part of Canon's professional L-series, the Canon EF 70-200mm f/4L IS USM boasts in-built image stabilisation. It's the IS in the name that distinguishes the Canon EF 70-200mm f/4L IS USM from the cheaper 70-200mm f/4L USM.

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

I am very pleased with this lens, I have used it a lot since I got it and very happy with the results of the photographs I have taken.

I bought this lens back in 2011, I still have it and it's as good as new - in pristine condition, functioning perfectly and it is in many ways my best lens. The things I like about are: Image-Stabilization - this lens benefits from excellent IS - it makes the lens more versatile, more useful and...

Oh man! This lens is some fun! Easy to use. Pictures are beautifully clear & brings you right into the action. Fast & quiet. Love this lens.

"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.

Quite simply an excellent lens. As sharp as primes in its telephoto range, great contrast and colour, and state of the art IS. What it gives up in maximum aperture to the f2.8 version can be forgiven considering it's half the weight and 2/3 the cost.

Very nice & great value for money..I am using this lens since one year

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.
