Telephoto lens newly equipped with an Image Stabilizer enabling hand-held shooting for easier movement. The fluorite element and two UD-glass elements effectively correct the chromatic aberrations prone to occur with telephoto lenses. With the EOS-1v and EOS-3, the AF speed becomes the world's fastest. To reduce the overall weight and enhance portability, the lens barrel and many other exterior parts use magnesium-alloy. Also, the detachable tripod collar revolves smoothly and locks securely.

Let's just recap what all the reviews say about this lens in one word: perfect.
My review won't add too much more to what's already been said, but I will point out a few things about this lens that I really like.
+ It's the sharpest piece of glass I've ever seen. This lens is sharper wide open than my 100-400 at 300mm stopped down to f/8.
+ It has 3 focus limiter switches. This takes a while to get used to, but it also makes the autofocus incredibly fast especially for distant moving targets.
+ It takes a 1.4x and 2.0x teleconverter incredibly well. Even with the 2x attached, the lens is still very sharp. When using the focus limiter, the autofocus with the 2x is still fast enough to capture birds in flight handheld. There's no appreciable difference with this lens bare and with the 1.4x teleconverter.
+ Attached to my 1D2, the autofocus is so fast I can't visually keep up with it sometimes. Yes, it's that darn awesome, and no I'm not kidding...
+ The focus preset system is not really intuitively clear, however, once you get it down, it's really really helpful for setting up your shots when you know where your target is going to be. Bigtime plus for tracking faster subjects in predictable paths.
There are no cons to this lens except one. It's HEAVY. I use mine on a tripod or monopod, however it can be use handheld even with the 1.4 attached for a good amount of time especially if you've got stronger arms and can hold it up.
Overall, if I could give this lens 10 stars out of 5, I would. I was worth every single penny.

I am not a professional photographer. I bought this lens from Ebay, used and without IS. The lens is very fast, sharp and sturdy. I like it very much. I used this lens to take pictures of deer in my backyard. But the lens is very heavy. You cannot use it without a tripod or monopod. However, I have a question and I would appreciate if you could spend a moment to share your valuable experience with me. Does this lens require a UV filter and a Polarizing filter? I bought two of these filters, each 110mm in size, thinking that I could install them at the front end of the lens. But there is no thread in the rubber-molded rim at the front end of the lens. I checked the Amazon specification above and noticed that a 52mm dropped-in filter is mentioned. (Nothing mentioned about any 110mm filters). Logically the only location for putting a 52mm filter would be at the back end of the lens. Discussing with a filter supplier in England, I was informed that there is a 52mm gel-type filter at the back end covered underneath a screwed-plate. This 52mm lens may have been put in there by Canon when the lens was built. I bought the 110mm filters from this filter supplier, then he asked me whether the 52mm gel-type filter is available in market. Now I have two problems to solve: (1) Do you use UV and Polarizing filters with this lens? If so, how do you fasten them to the lens, and (2) Is the 52mm filter available in market? and where to get it from? Thank you.

Love:
- Sharp wide open and that is what counts (sharpens nicely with software).
- Sharpens more when stopped down an f-stop (outstanding resolution).
- Fast auto focus (fastest I have seen).
- Solid build (switches and rings are precise without play).
- Replaceable flat front glass which protects the adjacent UD element.
- Autofocus stop buttons.
- Dust and water resistant.
- Programmable preset focusing.
- Removable tripod collar.
Like:
- Optical image stabilization (wish it had the newer 3-4 stop version).
- Hard case (good for storing lens in your house, vehicle or airplane).
- A good way to meet nice strangers (especially the ladies) who approach and raises questions about the lens.
Dislike:
- E-145 lens cap (will dislodge if lens is carried in the field with the hood reversed).
- Paint will come off on the barrel at the ET-120 lens hood contact point.
- Need to buy Canon touch up paint to repaint lens hood contact point on barrel.
- Not a dislike but the strap's buckle can scratch the prism housing (position the buckle close to the lens away from the camera).
- Weight (not really hand holdable and needs at least a monopod).
- Cost (but it's faster and sharper than the Canon 300/4 versions).
This is the sharpest and fastest autofocus lens in my collection. The 70-200/4 IS is a close second.
Please refer to my uploaded photos.

I shoot track & field, cross country, and nature photos with this lens, and the sharpness and the image quality are unparalleled. After 4 years I'm still amazed at what this lens does. Flawless.

Oh my goodness...what a lens! This is such an awesome lens. I wrote a review for the 35mm and said that it was the sharpest lens Canon made but oh god was i wrong. This lens is so darn sharp at all stops. It focuses so quickly and takes the most insane photos. It is a little heavy and you will draw a few looks carrying it around. I went to Yellowstone with this attached to my 5D Markii that already had a grip and people were literally staring at me and pointing. It felt a bit strange. Anyway the quality of the build is the best you can get. It is expensive but really worth the price. You will not regret it at all. It works great with the extender 1.4x. To see some of my shots with it go to my site:
