From the Manufacturer
High-performance, L-series telephoto zoom lens combining light weight and compactness with an f4 maximum aperture. Inner focusing and the ring USM enable quick and quiet autofocusing. Also, a circular polarizing filter can be attached and used without difficulty because the front lens element does not rotate during focusing. The tripod collar (sold separately) is the same one used with the EF 300mm f4L USM.

Customer Reviews

Top image quality
This lens is simply flawless - it has to be the sharpest of all the Canon lens and is right up there with the primes - a truly amazing feat.

Not only is the 70-200 f4 an optic treat, but it is light and easy to carry, easy to focus, very reaonably priced: just an all-around superior lens. I owned the 70-200 f2.8 and sold it after using this lens for a little while. This one is definitely sharper and about a pound lighter.

There have been many detailed reviews of the canon 70-200 f4. Try one. You won't be sorry. One of 2 lens that I simply would not part with and I have quite a few top quality L's in my camera bag.

Awesome IS!
I recently took delivery of this lens, and have had a few days to play around with it. All I can say is it surpasses any IS product I have ever used. I have taken some test shots at 200mm with a shutter speed of 1/30 and I can count the dust specks on the object I was shooting. Unbelievable. One note of caution, just so you are not disappointed, IS does NOT reduce blur from SUBJECT motion. When trying photograph my puppy, he is usually responsible for the blur, not the lens or me.

I was worried about not getting the f/2.8 model, but didn't really want to lug around a lens that large. I'm glad I got the f/4 version. This lens has a nice weight and diameter that makes it very comfortable to carry around.

One other note, when you depress the shutter, and the IS engages, the IS is slightly noisy, but only loud enough for the photographer to hear.

In all, this lens lives up to it's reviews. I'd get it again in a heartbeat.

I bought this lens after reading all the reviews on amazon. I was going back and forth between the f/4 with image stabilization and without. It is a significant amount of money paying for IS but I'm glad I did it because the lens is really sharp, I don't have to worry about shaking, and it'll last forever. So far its been very easy to use even for a novice like me.
