The EF-S 18-55mm F3.5-5.6 looks destined to carry the flag as the kit lens sold with virtually every Canon D SLR over the next few years (and that counts as an awful lot of lenses), so it really needs to perform well in the face of some impressive competition. Fortunately for them, Canon have indeed upped the ante with this new lens; it's much better than its predecessor, especially in terms of sharpness in the corners and at wider apertures, and with reduced chromatic aberrations to boot. Indeed overall it's an extremely well-behaved little lens, with very few nasty surprises for the user, and a remarkably good image stabilization unit; indeed Canon's main concern may ultimately become whether users have as much incentive to upgrade to more expensive optics as they did before. The Canon 18-55mm f/3.5-5.6 EF-S IS Lens is a standard zoom lens that features the smaller size image circle, exclusively designed for EOS Digital Rebel and other cameras using the "APS-C" size sensor. The focal length is equivalent to approx. 28-90mm in 35mm format. This makes it ideal as a basic everyday lens. This lens features Canon's optical Image Stabilizer technology, which provides up to 3-4 stop compensation for image blur caused by camera shake and slow shutter speeds. This ensures clear, crisp images, even in dim light. Designed specifically for digital photography, the lens has specially shaped lens elements and Super Spectra coatings to suppress ghosting and flare, which can be caused by reflections off digital camera sensors. An exclusive optional lens hood can further reduce the incidence of flare. Note! Only fits on the EOS 10D, 20D, 30D, 40D, 50D & 60D or Digital Rebel XT XTi XS XSi T1i T2i T3 T3i SLR cameras
