Overview

The Canon EF-S 24mm f/2.8 STM is a compact pancake lens for APS-C cameras, offering a 38.4mm equivalent field of view. Optically, it delivers great sharpness at all apertures, with well-controlled distortion and chromatic aberrations, though bokeh can be busy. Build quality is robust and less plasticky than budget lenses, and the STM motor provides quiet autofocus with smooth manual override. It is an excellent value at $150, ideal for street photography and as a lightweight walk-around lens for Canon APS-C shooters.
