Pros: Very sharp images, excellent color rendition, typical "L" construction, just a wonderful lens.
Cons: Zoom feature can be hard to adjust smoothly even with adjustable friction feature and it is rather slow above 300mm.

I've only had the lens for about a month, but have had the opportunity to take about 300 photos. It produces very sharp and accurate color exposures when mounted to my 5D. I took several good hand held shots at 1/60s at 350-400mm due to the effective IS Canon has only improved over the years. I do not particularly care for the push-pull zoom design because although adjustable it is either too loose or when tightened zooming is "jumpy" with definite stick-slip. Construction otherwise is rock solid and performance leaves little to be desired aside from what I mentioned about the relatively small maximum aperture.

Pros: well built and quality at a reasonable price, esp for the range and the IS.
Cons: I hate the push-pull zoom system!

I like the lens and the images that I get using it, I just dont like the push-pull design in general. Otherwise its a great piece of glass. I gave it a 10 based on the image quality, as that is the most important part overall, that and the build. Just like with all other good pieces of glass, make sure you use a good filter on it, like a B+W or Heliopan. They are ground glass, dont ruin it with a cheap window pane piece of glass like the Tiffen and hoya and the other brands!

Pros: Sharp focus, light weight, rugged
Cons: f/5.6 at 400mm, attracts dust internally, prone to electronic problems

I have owned this lens for 2 years and shot more than 10,000 images with it. Since I had it calibrated with my 1D MkII and 1D MkIII last month it has been superb. Extremely sharp images. Two minor problems: 1. The push-pull zoom is sticky (does not pull smoothly) and, 2. the push-pull design does suck dust into the lens (vacuum cleaner effect), where it cannot be removed. A bigger problem however, is that some 100-400 lenses apparently have electronic problems. Last year I had 4 instances of the camera "locking up" (wouldn't take a photo). Someone told me to turn power off, take the lens off, and reattach it. I did and it worked fine. Disconcerting, but fixable. After owning the lens for 18 months the camera once again locked up, but this time I could not turn power off. I had to take the battery out to turn it off. I reseated the lens, reinstalled the battery, but no luck. Camera wouldn't fire. I thought it was a camera malfunction so I attached the 100-400 to my back up camera to continue shooting. That backup camera exhibited the identical problem: it, too, wouldn't fire. Both bodies were dead. I sent both bodies and the 100-400 to Canon Factory Service. They confirmed that the 100-400 lens malfunctioned and shorted out the electronics in both cameras. They fixed the problems (no charge) and I have been happy with the lens ever since. It is a perfect focal length for my needs. (However, I will be the first in line to buy an f/4, non-push-pull version of this lens whenever Canon decides to redesign it.)

Pros: Versatile, great IQ
Cons: none

This is a fun lens. 400mm on a crop body gets you some serious reach. I primarily use it for landscape photography, but it is a little heavy for longer hikes and backpacking. For this I prefer the 70-300IS... But if I'm shooting near the car this is definitely my first choice for telephoto landscapes.

I also shot a few PGA Tour events with it, and was pleasantly surprised at its performance. Of course golf is a fairly stationary sport played in good light, so this shouldn't have come as too much a surprise...

Some criticize the lens for its performance wide open at 400mm especially. But check out this crop, wide open at 400mm:

Sure it's no 400 2.8, but it also doesn't cost $6500 and doesn't weight 12 pounds... It is an excellent and versatile value.

Hope this helps,

Pros: Sharp focus, image stabilizer, good price
Cons: f/5.6, push-pull zoom

I wanted to purchase a telephoto lens to round out my camera equipment bag. After months of research and interviewing other photographers I purchased a 100-400 IS f5.6. On my first outing of shooting snow geese and tundra swans I thought the results were not as clear as expected. I re-read the instructions and tried again with no improvement. Called Canon technical support, sent the lens back and it turned out the back focus was not working properly. On my next shoot I was thrilled with the results clear focus, image stabilizer works well for taking bird photos.
Used with a polarized filter and f22 to f32-produced waterfalls with a beautiful soft veil. At an evening pro baseball game I was able to get shots of my favorite players in action. This lens doesn’t work well in low light but I mainly bought it for photographing nature, air shows and sporting events. I’m pleased with this lens and would recommend it to a friend.
