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.

I enjoy using this lens for outdoor portrait photography, some wildlife and selective landscape photography. I've had many good indoor shots as well. The autofocus is fast and silent, the image sharpness is INCREDIBLE. The most surprising feature is how lightweight this lens is, despite feeling well built. At half the weight of the f/2.8 version, this one is easily handheld. Use a 1.4x or 2x extender for longer range. I also like the included lens hood.
Pros: Fast auto-focus, Superior build quality, Super-sharp images
Cons: a little pricey
I debated for a long time before shelling out this much on s lens. But I love it, the quality, the vbuild, the feel. Absolutely love the IS; have gotten some great deer pics at sunset. Astonishing, Recently was taking my grandson's Senior Pix and threw this lens on at the end and thought "this is why I love this lens,"
Pros: Fast auto-focus, Superior build quality, Super-sharp images, creme de le crop
I have been a member of the Canon system for over 25 years. My first purchase was the Canon A1 camera. I graduated to the excellent Canon F1 and shot film with FD primes for years. For some time now, I have been a member of the digital age. I have always compared my current lenses to the old FD line. I recently purchased the new 70-200 f/4 IS USM L lens and have repeatedly been blown away by it's image quality, rugged design and super fast ultrasonic focusing ability. This lens delivers sharp, contrast rich images on a routine basis. The image stabilization is an excellent addition to this powerhouse product. It will provide you with the ability to capture your images at an incredible four stop advantage. It is much lighter and in my opinion sharper than it's brother 2.8 version. If your an action sports photographer go with the 2.8 version. Everyone else run to your nearest Canon authorized dealer and purchase this lens. You will not be disappointing. I am Proud to be a member of the Canon 70-200 f/4 IS USM L lens family, this lens is worth it's weight in Gold.
