Amazon.com Product Description
Although the Canon EF 135mm f2 L USM lens has completely automatic focusing capabilities, you can still take advantage of its manual focus function, even while the camera is in AF mode. The two UD glass elements help to correct residual chromatic aberrations, giving your images outstanding sharpness and color. This lens is great for shooting under low-light situations such as indoor sporting events or portraits where you want a blurred background. The EF 135mm f2 L USM lens is compatible with extender 1.4x and 2x; these can increase your camera's focal length to 189mm f2.8 with extender 1.4x or 270mm f4 with extender 2x while still using the AF function.

From the Manufacturer
One of the finest lenses of its type in the world today. This magnificent telephoto lens uses two UD-glass elements to provide incredible sharpness and contrast, even wide-open. It's perfect for outdoor portraits, but comes into its own in low-light situations. It focuses down to 3 feet (0.9m), and is fully compatible with both the EF 1.4x II and 2x II tele extenders.

Long and Fast
A telephoto lens is essential to any serious photographer. For sports action, you will need a fast shutter speed and a long focal length. A large maximum aperture allows a faster shutter speed. In this telephoto lens line-up, the focal lengths range from 135mm to 300mm. If you want compactness, choose a lens with a smaller maximum aperture.

Canon EF 135mm f2/L USM Lens Is Sweet
I don't really have much to say other than I really enjoy this lens. It's super sharp and great for low light conditions. You can read all sorts of fantastic reviews regarding this lens pretty much everywhere online. It's also very reasonably priced for a Canon 'L' lens. If you have the spare change, go out and buy one. You won't be disappointed :o)

Amazing lens for indoor sports photography
I've had this lens for over 2 years now, coupled with my 20d, and it's given me amazingly sharp results at WNBA basketball games. The Key Arena is where I shoot from the stands as a fan, and I usually shoot vertical format. A white lens wouldn't be allowed into the Arena unless I was a pro, so the black color and small size of the 135 doesn't raise any red flags. Having a fast lens allows me to go to higher shutter speeds, freezing some very fast action. A fellow photo fan recommended this lens to me, and said that it was so sharp, I should forget about zoom. Instead, I should take shots and crop to achieve different compositions, and he was so right. I'm extremely glad I took his advice! If the focal length suits your needs I'd go for it without hesitation.

The best EF lens I own, by far
Previously, I relied on Canon's EF 28-135mm f/3.5-5.6 IS lens for modest telephoto images. There is *no comparison* between the images that the 135mm lens produces and that zoom. The difference is not merely that the fixed lens is a lot faster (in practice, I rarely go wider than f2.8 anyway; the depth of field becomes too narrow for my taste). Rather, the pictures are sharper, colors are brighter, and people seem to have a strong preference for the bokeh in pictures taken with this lens. More than once, I've been asked "How do you blur the background like that?"

You might expect that a fast lens is particularly useful indoors in natural light, and it does produce great results in such conditions, but I've also taken wonderful photos with this lens of children playing outdoors.

No image stabilization, but I've never missed it. I've had mixed results with other Canon lenses but this is by far the best of the lot, I've no criticism of it at all.
