L-series super telephoto zoom lens equipped with an Image Stabilizer. The fluorite and Super UD-glass elements largely eliminate secondary spectrum. The floating system also ensures high picture quality at all focal lengths. The Image Stabilizer has two modes and it is compatible with Extenders 1.4x II and 2x II.
I use primarily for wildlife photography, I love it's speed and zoom. The push-pull is a little different to get used to but easy to get the hang of. The 1.4x III extender works amazing with this lens, however the 2x II extender does not work in auto focus. But I rarely pair them together any way.
400 mm really gets you close to the action. I have used this lens from the deserts of Arizona to the islands of Alaska and it has never disappointed me! It's an incredible lens!!

At some race car tracks your allowed to be in the hot grid area while the cars are on the track. I used this area to capture eyes in the helmet while flat out on the straightaways The eye expression is priceless. This lens made that shot effortless. And as for wildlife this lens works well also. For me the wide uses of this less made the cost very reachable.

A Lens to Own and Use!
I've only had this lens for about a week but it's been on my cameras 90% of the time. I've used it on a 60D with the 1.4x III and by itself. The auto focus is fast and reliable. The sharpness is outstanding. I shot some photos of a green winged teal duck this afternoon. Every feather is clearly defined. Yes, the push/pull design seems a little like a throw back, but nostalgia never hurt anyone.

Really COOL Lens
I have had my EF 100-400 for about three days not got a lot of use out of yet (because the weather has been poor) BUT I will. I got this lens because it was a zoom so it was more versatile than a prime lens and because it had the extra reach that my standard telephoto did not have. I cannot wait to get out into the field and give it a complete run down and a good day’s work and send it through the passes. I got it mainly because I like to take nature shot of wildlife and landscapes. I thought the price was a lot, but reasonable, considering that there are some lens that cost A LOT more than this one!!
The Build is nice it feels sturdy and well made. So far the shot in the poor weather have been great, real sharp and crisp images and I have found that it is really easy to take hand held shoot with this thing. I have a Anna’s Hummingbird that has a territory outside my house and I have spent a good few hours taking pictures of him and they are great. I really cannot wait to see what this lens is capable of in better light conditions!! When you first pick it up it feel like it weighs a TON but once it is on the camera and have it on your shoulder it really is not so bad! I really like that the auto focus does not change when tracking subjects, many time with other lenses i have been following an subject and the auto focus will focus on something else and i would loose my target!!
Overall good build quality and great lens to add to a kit, especially for wildlife nuts like me.
