The EF 50mm f/1.8 STM Lens from Canon is a compact, normal-length prime well-suited to everyday shooting. Additionally, an STM stepping AF motor is used to realize quick and near-silent autofocus performance along with full-time manual focus override. Bright f/1.8 maximum aperture enables control over depth of field for selective focus applications and also benefits working in low-light situations. An STM stepping AF motor realizes smooth, near-silent autofocus that is complemented by advanced AF algorithms and a high-speed CPU for fast AF performance. Additionally, a full-time manual focus override is also available. The redeveloped physical design incorporates a metal lens mount for durability as well as a re-located focusing ring to maintain a compact form factor.
