The Canon EF 50mm f/1.8 STM is a lightweight, affordable prime lens designed for full-frame Canon EF-mount cameras, while also delivering an 80mm equivalent focal length when used on APS-C models. Known as one of the most versatile focal lengths available, this compact 50mm lens is ideal for everyday shooting, creative portraits, shallow-focus photography and low-light scenes.

With a bright f/1.8 maximum aperture, this lens allows you to create sharper images with less motion blur and shoot comfortably in low-light environments without needing a flash. It also gives you precise control over depth of field, making it easy to isolate your subject and achieve beautifully blurred backgrounds.

Superb image quality in a compact design

Despite weighing just 160 g and measuring only 40 mm long, the EF 50mm f/1.8 STM delivers impressive image quality. Individual lens elements feature Super Spectra Coating, which helps to reduce flare and ghosting, while maintaining strong contrast and accurate colour — even in harsh or backlit conditions.

The rounded 7-blade diaphragm produces a pleasing out-of-focus look, making this lens especially well suited to portraits, detail shots and creative selective-focus photography.

Smooth, quiet autofocus for stills and video

The built-in STM stepping AF motor provides fast, smooth and near-silent autofocus, making it ideal for both photography and video recording. Combined with advanced AF algorithms and a high-speed CPU, the lens delivers reliable focusing performance while also offering full-time manual focus override for fine adjustments.

When shooting video, STM technology ensures steady and quiet focusing so your soundtracks capture only the surrounding sounds — not the lens motor.

Built to be taken everywhere

With its compact size, lightweight build and redeveloped physical design featuring a metal lens mount and a repositioned focusing ring, the Canon EF 50mm f/1.8 STM is designed for durability while remaining easy to carry wherever you go.

From everyday photography to creative low-light shooting, this versatile 50mm prime lens is a powerful addition to any Canon EF-mount camera kit.
