Product Description

This high grade telephoto zoom lens responds to the exacting requirements of professionals and advanced amateurs, yet at a reasonable price. One artificial crystal fluorite and two UD (Ultra-low Dispersion) glass lens elements in its optical system eliminate secondary spectrum, which is often the Achilles' heel of telephoto lenses resulting lower picture quality. These elements assure high resolution and high contrast throughout the entire zoom range. The latest optical design gives a minimum focusing distance of 1.2m and 0.21x maximum magnification. This lightweight, compact zoom lens, having the same level of optical performance as EF 70 - 200mm f/2.8L USM, assures good portability and operability. The ring USM (Ultrasonic Motor) and inner focusing system achieve high-speed silent autofocusing. Manual focusing, even while in AF mode, is possible thanks to full-time manual focusing mechanism. Extenders EF 1.4X and 2X can be used with this lens, and the optional Ring Tripod Mount A (W) is being marketed concurrently.

Amazon.com Product Description
Capture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 70-200mm telephoto zoom lens. This high-performance, L-series telephoto zoom lens is distinguished by such features as an f/4 maximum aperture, an inner focusing system, and a ring-type ultra-sonic monitor (USM). The last two features combine to deliver quick and quiet autofocusing--a priority for many amateur and professional photographers. In addition, photographers can attach and use a circular polarizing filter without difficulty because the front lens element does not rotate during focusing. Compatible with the same tripod collar (sold separately) used with the EF 300mm f/4L USM lens, the lens carries a one-year warranty.

From the Manufacturer
A truly professional L-series telephoto zoom lens, with reduced size and weight for applications where portability is important. Superb optically, it combines a Fluorite element with two UD-glass elements for outstanding contrast and performance. Its ring-type USM is fast, silent, and permits full-time minimum focus, as well as the closest MF of any of the L-series 70-200 designs. It’s also compatible with EF Extenders 1.4x II and 2x II, and accepts an optional accessory tripod collar.

Isolate the Interesting Part
The eye tends to see the whole rather than the individual parts. It also sees what’s near and not what’s far. By bringing attention to those things missed by the eye, you can create many interesting pictures. It could be the grimace of an athlete, the grill of a classic car, or a girl against a blurred background. Telephoto lenses can also compress images to give dramatic effects. You are limited only by your imagination.

Customer Reviews

Great Pictures
I was tired of looking through my camera with the lens that came on it and seeing the subject close up;then when you actually print it they are not as close as they looked. This lens is great. The quality of the picture is wonderful. I can take pictures of my grandchildren's football games from the stands and get pictures that look like I was right beside them. I can also take a close up of a flower and the quality is perfect and very close up. It is great.

very nice lens
very nice lens: light weight, excellent quality, close to the f/2.8 but better price = excellent value

Canon 70-200mm f/4 L USM Lens
One of Canon's best in quality... This lens exceeds my expectation, though I did my homework prior to purchasing and it's performance is awesome... It is quick in focusing and produces spetacular photos...

This is a non-IS lens, so unless your very steady, it is advised to rest lens on a bean bag or brace yourself against something... I like bird photography so I use a tripod with this lens with a 1.4x Tele-Conveter connected and it produces really sharp photo's... Ultrasonic Motor is quiet and very fast...

For the price this can't be beat... It's an L lens which is Canon's best line.. Excellent build and the telephoto is conceled within the lens and does not extend...
