    Overview

    The Canon EF 22-55mm f/4-5.6 USM is a compact, lightweight zoom lens originally designed for APS film cameras but fully EF-compatible. Optical quality is mixed: it offers decent sharpness when stopped down to f/8 (Thomas Perry), but suffers from massive barrel distortion at the wide end (Thomas Perry) and noticeable chromatic aberration (Mark). Build is plastic with a plastic mount and no distance scale (Mark), though the Micro USM provides fast, quiet autofocus. It suits budget-conscious users seeking an ultra-wide zoom for crop-sensor cameras, especially the Canon 1D Mark IV (Mark), but requires careful handling and post-processing correction.
