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 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.

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

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 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.

I own this lens which works perfectly. Good thing is that, you will get sharpest image while cropping the aberrant sides and corners of the frame. Image quality is simply awesome. 5 stars for that. !!

i love this lens, paired wit the 7D action shots are a pice of cake and also is versatile when shooting other stuff

Good Product~!

Great for shooting my son's flag football games!

Awesome Low Light Lens; Consistent Output; Fast / accurate auto-focus; Strong Construction
