Features
Compatibility: The Canon EFS 55-250mm f/4-5.6 IS
telephoto zoom lens is compatible with
select Canon EOS DSLR cameras, including the following - EOS 40D, EOS 30D, EOS
20D, EOS Digital Rebel, EOS Digital Rebel XT, and EOS Digital Rebel XTi.
Telephoto Zoom Lens With Optical Image Stabilizer:
This telephoto zoom lens is designed with Canon's
Optical Image Stabilizer technology while retaining compactness and lightness. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the
35mm format (when used on Canon EOS cameras compatible with EF-S lenses), and
the image stabilizer effect equivalent to a shutter speed about 4 stops faster
than the same size lens without Image Stabilizer. In other words, if the slowest
shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a
second, with Canon's 4-stop stabilization correction, you could hand-hold at
shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens
element to correct chromatic aberration for excellent image quality throughout
the zoom range.
Auto/Manual Focus Modes: To shoot in autofocus mode, you must set the focus mode switch on the lens to "AF."
To manually focus the camera, you must set the switch to "MF," and focus by
turning the focusing ring.
Optional Accessories (available
from Canon): You can attach optional filters (58 mm) to the filter mounting
thread on the front of the lens. You can also use the following optional
extension tube: EF 12 II or EF25 II. In addition, by attaching the optional 250D
or 500D (58mm) close-up lens
enables close-up photography. Magnification will be 0.23x-1.42x for the 250D
close-up lens and 0.11x-0.86x for the 500D close-up lens.
