I upgraded to this I series lens from a Tamron 200-500 telephoto lens and I am very happy that I did.The image quality is noticeably clearer especially at 800mm. (I'm using a Canon 2x extender). It's heavy but you'll be using a tripod anyway. Hey, it's a Canon!

As an amateur nature photographer I wanted to purchase a lens that would let me get closer to my subjects, (affectionality referred to as critters), without disturbing them, while, feeding, flying, or playing. This lens really delivers great results. My bird in flight shots are crisp and clear. The details that I now obtain are vivid and it has enabled me to finally achieve the nature photos that I wanted without spending thousands of dollars.
I would highly recommend this lens to nature or wildlife photographers.

Got great pics with this lens. Took it out for a one week safari earlier this month and the pics were the best I have ever taken. One minor complaint -- wish it has a lock, as it so big and heavy, that without a lens lock, it sometimes can slide out unexpectedly.

This lens is great for nature and bird photography as long as you have suitable lighting conditions. It's at its best in soft natural light (overcast days), and performs very well in bright sunlight. Tough to get decent shots in low light with moving subjects. Fine for static subjects in low light. Not recommended for use with a 2x teleconverter unless you have a pro camera body (such as a 1Ds MK II) because you will have to focus manually. Works better with a 1.4x converter for greater reach of far away subjects with a 50D type body. Since it's a telephoto, it is not quite as sharp at each end of the focal range, but I find 200-300mm works extremely well. This lens is not extremely heavy, but it does get tiresome to handhold after about 30-40 minutes, at least for me, so a tripod or monopod is highly recommended as a stable support for the best images if your arms are weak and you will be shooting for more than an hour. I use mine on a Wimberley Head and Gitzo Systematic tripod. The zoom feature is a push-pull style that takes some getting used to, and I find it a bit cumbersome. In order to change focal lengths you have to loosen and tighten the zoom ring tension, or set it just so, and I find it a challenge to keep a specific tension without accidentally tightening or loosening the ring while hand-holding and gripping the lens barrel for support. The IS feature works well for hand-held shots. For birds and wildlife, this is an all-around good starter L-series lens. If I had more money to spend, I would have gone for the 300mm f/2.8 IS or 400mm f/2.8 IS however.

I just got my Canon 100-400mm IS L lens last week. I took it out and gave it a workout yesterday at the Zoo with what may be a once-in-a-lifetime opportunity: shooting baby lions that are rarely seen by the public. Prior to this, I was using a Canon EF 70-200mm f/2.8L IS USM Telephoto Zoom Lens for Canon SLR Cameras with the Canon EF 2X II Extender Telephoto Accessory when I needed more than 200mm. A website reviewer's photos demonstrating how much blur the extender adds convinced me to sink the necessary funds into the 100-400mm lens. And boy, was it worth it! I had struggled with how soft images came out with the extender, even when I used a tripod and a shutter release. But I did all handheld work yesterday with tumbling, rambunctious baby lions in cloudy conditions, and got fantastically sharp, close photographs, even at 400mm.
There are a couple of things people seem to complain about with this lens. First, that it's heavy, and second, the push-pull zoom. I want to address both.
Weight: Yes, after shooting for 3 hours with this 3-pound baby, my arm was tired, but it wasn't a hardship by any means, and I wasn't sore the next day. The lens also has a tripod ring on it so when you use a tripod you can mount the lens directly onto the tripod, if the weight really bothers you. The nice thing is that it's a solid, well-made lens.
Push-pull zoom: I expected to find it frustrating, at least until I got used to it, but I got used to it in minutes and found it was actually beneficial -- I could shift from 100 to 400mm (or anywhere in between) much faster than I could have if I'd been twisting to zoom. I also quickly got into the habit of twisting the resistance ring that changes how easily the push-pull mechanism works. As soon as I changed the focal length, I'd twist to keep it there, but not so tightly that I couldn't change again if I wanted to. I had no problems with the lens slipping out to its full extension when I didn't want it to, even when I quickly lowered the camera. (Had to do that several times given that Mama Lion didn't like big camera and lunged the fence more than once. It was a nice, sturdy fence, so I was safe, but I didn't want to upset her, nor did I want a big lunging lion looming between me and the babies and blocking the view.)
Auto-focus is quiet and quick, and though once in a while I had a bit of trouble focusing through fairly close-set bars, I got so many amazing shots that I can forgive the very few I missed while the focusing was struggling. I also used the lens with a pacing tiger, and the lens and camera (EOS 40D) were able to work quickly enough to get far more sharp pictures than blurry, even when the tiger was close and moving fast.
The Image Stabilization is amazing. Neither of my other two lenses has it, but I'd never buy another lens without it!
You can focus in on subjects as close as 1.8m, which is great with animals who are constantly doing the unexpected. When the tiger came right up to the glass, I could take a few steps back and get photos that were as sharp as the ones I took of the animal farther away.
Finally, I noticed that at 200mm, the fence was still in the picture. At 400mm, the fence vanished completely, even when I (and the cubs) were fairly close to it (though not on the same side! :) If I'd been relying on my regular lens and the extender, I know the final shots wouldn't have looked like they were taken in the wild -- which is always the goal!
Bottom line: fantastic investment for a fantastic lens
