What else can be said about this lens...

Its a case of you get what you pay for and this lens delivers! I'm still adjusting to the push pull and will know more when the amateur football season begins but I don't expect it to be an issue at all. Buy It!!!

Canon EF 100-400mm F4.5-5.6 IS USM Telephoto Lens

I am very pleased with this lens. Its great for sports, which is what I mainly have been shooting with it. The push pull zoom is a great feature although locking and unlocking it in place takes a little time to get used to. The Image Stabilizer is wonderful as always. Can't think of anything else to say except it does what it says and I'm glad I own one!

Be careful!

I have been a dedicated amateur for over 40 years and recently bought a Canon 40D with the 28-135 mm IS lens. My next lens was the 17-40 mm L, a terrific lens in every way. When it came time to look for a telephoto, I naturally leaned toward the L series and the 100-400 IS L made sense. I wish I had read the reviews more clearly and saved myself and Amazon some trouble! This is a wonderful lens! The clarity is amazing and the IS a joy to use. If you are a pro and don't mind lugging this "tank" around, it will do what you need. If you are like me and need a travel zoom, this is way over-kill. I sent it back and got the 70-300 IS non L and I love it. It's light weight and does a good job. I know it's not as good as the L, but head to head, taking the same shots with the 40D at the same time and viewing on an Apple 23 display, I can't tell any difference. Bottom line, if you need this quality and don't mind the weight, size and price, go for it. It's one of the best!

Low Light Buster

I found out that hand held at 1/250 sec shutter, f/8.0, ISO 200, cloudy on WB, AI SERVO, internal flash on are the best settings for this lens on an EOS XSI body. Details are just so crisp, clear and vivid with less grain and still be editable in Photoshop by just changing a little on the brightness and contrast as well as some cropping.
I am waiting everyday to be cloudy or set the cam to cloudy early in the morning or late in the afternoon to optimize my lens!!!!!
People are saying I'm crazy to use my camera and professional lens on dim lit environment but this is where I am getting the best of this lens.
Some reviews stated that the 400mm prime is a tad better than this lens but the best lens also depends on the user on his purpose to taking pictures coupled with some creativity on photoediting.
At this point buying a 400mm prime is out of my mind, I should be focused on buying 500mm or 600mm or even higher if I have the cash handy.

Excellent lens quality, but heavy and increases maintenance

This is an excellent lens. We bought it because my husband enjoys action photography and I enjoy wildlife photography. The lens quality is excellent and the zoom is very handy, however there are some disadvantages. This lens is very large and requires a sturdy tripod, hence the tripod mount built into the lens. The bellows function that allows the zoom tends to blow dust into the sensor, increasing the maintenance required on any camera used with this lens. When used with a doubler, this lens can only be focused manually. Also, this is an f4.5-5.6 lens, which is adequate for bright light, but frustrating in many situations when you're used to f2.8 or better.

The Canon's L-series super telephoto zoom lens is 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.
