Canon 100-400mm Zoom Review
The lens is suprisingly easy to handle and hold. Canon has kept the weight to a minimum. The image stabilization works very well and the lens takes very good handheld photos. Selected this lens over the shorter telephoto with a 1.6x, because of the much better weight disbursement.

Great Lens for outdoor events
What can I say? This is a great lens for everything under the sun. It is worth every penny I spent on it. Most of the pictures I take with this lens are of track meets and other sporting events. I purchased this coupled with the 2x converter. One thing that I didn't realize when I purchased the package was the autofocus does not work through the 2x converter. Things move too fast for manual focus at track meets and air shows. So it is rare that I use the 2x converter. I got this lens last year in time for the snowmobile season to start. It is tough and goes with me everywhere. The detail is just incredible. I would recommend this for outdoor use. Not quite fast enough for indoor without a flash. If everyone is standing still, it does a great job, but this lens belongs outside.

A must have telephoto lens!
I have used this lens for some years now, and even though I own other L lenses including the 70-200mm f2.8 and the f4, I prefer to use this lens because it is more versatile. This lens produces images, wide open, throughout its zoom range that are comparable in sharpness and color to the 70-200mm f2.8 (which is as sharp as you can get in zoom lenses). What's more, this lens beats all other lenses when it comes to macro photography in the field. This lens has maximum magnification of 0.20 at 400mm. The images are so sharp that I can see pollen, tiny barbs and hair on insects while shooting handheld from 6 feet away. The background blur is superb. The only other lenses that I carry are the 24-70mm f2.8 and the 50mm f1.4.
