An excellent compact standard zoom lens, designed for IX 240 SLR cameras, EOS IX series. However, this lens is fully compatible with 35mm EOS series SLR cameras as well. A replica aspherical lens element (molded plastic on the glass spherical lens(2nd)) provides sharp definition throughout the entire zoom range. Featuring both an ultra-wide-angle 22mm focal length and compact optical system, this lens has a micro USM (Ultrasonic Motor) control for silent, high-speed AF. A wide zoom ring ensures smooth zooming. When fitted on an IX 240 SLR camera, the zoom range is equivalent to a 28-69mm focal length on a 35mm camera. The optical system consists of only ecologically sound lead-free glass lenses.
