Canon EF-S 18-55mm f/3.5-5.6 Lens

The Canon EF-S 18-55mm f/3.5-5.6 Lens (the original, non-stabilized version) is a compact standard zoom lens designed exclusively for APS-C-format Canon DSLRs, serving as Canon’s original kit lens for its earliest EF-S mount camera bodies. It delivers an accessible 28.8-88mm equivalent focal length range, covering wide-angle through short-telephoto perspectives suited to daily snapshots, landscapes, and environmental portraits.

Optically, the lens is built from 11 elements in 9 groups, including a high-precision aspherical element to help correct spherical aberrations and distortion for consistent image quality throughout the zoom range. A 6-blade diaphragm (circular for the first two stops) contributes to the lens’s background rendering, with a variable maximum aperture that steps from f/3.5 at 18mm through f/4 at 24mm and f/4.5 at 35mm to f/5.6 at 55mm, down to a minimum aperture of f/22-36.

Autofocus is handled by a USM (Ultrasonic Motor) system on most production versions, delivering reasonably quiet, high-speed focusing performance. The lens has a minimum focusing distance of 0.28m (9.8 in.) across the focal range, yielding a maximum magnification of 0.28x at 55mm.

Build quality uses a lightweight, all-plastic exterior, including the barrel, switches, and mount, with a rubber bumper on the rear to protect it when set down without a rear cap. The lens accepts a 58mm plastic filter thread and extends somewhat during zooming and when focusing closely. It weighs approximately 182.8-190g and measures approximately 68.5 x 66mm. As an original, non-IS version, it does not include image stabilization, a feature later added in subsequent EF-S 18-55mm IS versions.

The lens is compatible exclusively with Canon’s APS-C EF-S mount cameras and cannot be used on full-frame EF-mount bodies.
