Overview

The Canon EF-M 18-55mm f/3.5-5.6 IS STM is a compact kit lens for Canon EOS-M mirrorless cameras, offering surprisingly sharp optics for its class. Optical strengths include good center sharpness, especially when stopped down, and well-controlled distortion, vignetting, and chromatic aberration. Weaknesses include corner softness wide open and at 55mm, and noticeable barrel distortion at the wide end. Build quality is above average with a metal barrel and mount, though the inner barrel is plastic. The lens features smooth STM autofocus and effective image stabilization. It suits EOS-M users seeking a versatile, lightweight standard zoom for general photography and video.
