Canon 70-200mm f/4L EF IS USM - Black

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. The L-series lens offers an Image Stabilizer that provides up to four stops of shake correction--a first for Canon IS lenses. The use of fluorite UD lens elements, meanwhile, produces an excellent optical performance in terms of resolution and contrast. Add in a sturdy housing with water- and dust-proof construction and you have a lens that's both portable and high performing. Other details include an f/4 maximum aperture, a ring-type ultra-sonic monitor (USM) that enables quick and quiet autofocusing, compatibility with circular polarizing filters, and a lightweight body. The lens carries a one-year warranty.Focal length: 70-200mm Maximum aperture: f/4 Lens construction: 20 elements in 15 groups Diagonal angle of view: 34 to 12 degrees (with full-frame cameras) Focus adjustment: AF with full-time manual focus Closest focusing distance: 3.94 feet Zoom system: 7-group helical zoom (72-degree rotational angle) Filter size: 67mm Dimensions: 3 inches in diameter, 6.8 inches long Weight: 26.8 ounces High-performance, L-series telephoto zoom lens combining light weight and compactness with an f4 maximum aperture.
