What reviewers say

Amateur Photographer and Digital Camera World praise the small size, low weight and useful everyday field of view. Both find strong image quality, but Amateur Photographer reports softer corners, vignetting and more distortion wide open. It also finds autofocus quiet and reasonably quick, while Digital Camera World describes the geared STM system as slower and more audible than lead-screw designs.
