The EF 70-200mm f/4L IS USM is a lightweight, compact L Series telephoto zoom lens with Image Stabilizer. The optical Image Stabilization in the new EF 70-200mm f/4L IS USM lens provides up to an incredible four stops of shake correction-a first for Canon IS lenses. The use of fluorite UD lens elements provides excellent optical performance in terms of resolution and contrast. These features, together with its water-and dust-proof construction, provide both the performance and portability to meet user demands.
Excellent lens I have had this for about 8 months sharp pictures even captures birds in flight! Very light for the zoom range, well thought out lens. Easy to focus or adjust the zoom while framing a moving subject. I use it with a 1.4xII and its still tack sharp even on off hand shots.

Worth all the lofty praise?
Worth all of the lofty praise? ABSOLUTELY! This truly is photography's Platinum Standard - whether using digital or that old-fashioned stuff, film. I reserve the description "perfect" for almost everything; this lens is a rare exception. No questions whatsoever, absolutely tip-top marks for astonishing clarity, sharpness, colour & contrast; lightning-fast USM auto-focus. On an APS-C (1.6X) sensor body, this shoots like a 112-320mm f/4 lens. It is - basically - a "do it all" telephoto zoom. Considered the f/2.8 version but the added price for the one extra stop just wasn't worth it - to me. The added size & weight was also a factor.

This lens is so good it is almost unbelievable. The color this lens captures is beautiful and is very impressive. The lens zooms in and out with ease and focusing is precise and easy to work in manual setting. The only issue I have had with it is when using it with a t5i during a sports game the autofocusing is slow, but upon asking other owner's of this lens with different cameras, they as well as I believe this is due to the fast pace of the switching focuses that comes with sports and the t5i only having 9 AF points, rather than a 1D-X's 60-something. Because of this when I am doing video or am in a close up shot I use manual focus, which is not a bad second option, this lens makes it very easy.

My 1st L lens
I debated for a long time before shelling out this much on a lens. I couldn't decide between it and the non IS version. I'm so glad I purchased this lens. A big plus to this lens is that it does not change length when you zoom. The images are really sharp, and the image stabilizer is a life saver when needed. This 70-200 is the best bang for your money, go buy this one. You will not regret it, that's for sure!
