The Canon EF 50mm f/1.8 STM Lens is a versatile standard prime lens designed for photographers who want excellent image quality in a compact and affordable package. Its 50mm focal length provides a natural perspective on full frame cameras and is well suited to portraits, everyday photography, street photography, travel and creative shooting.

The wide f/1.8 maximum aperture allows more light to reach the camera sensor, making the lens particularly useful in indoor and low light conditions. It also allows photographers to create a shallow depth of field with pleasing subject separation and soft background blur. The seven blade circular aperture contributes to attractive out of focus rendering.

For focusing, the lens uses a gear type STM stepping motor that provides smooth and quiet autofocus. This makes it useful for still photography as well as video recording with compatible Canon EOS cameras. The lens also supports full time manual focus adjustment, giving photographers greater control when precise focusing is required.

The lens features a six element optical construction in five groups, a 46 degree diagonal angle of view and a 0.35 m minimum focusing distance. It accepts 49 mm filters and provides a maximum magnification of 0.21x. Its compact 69.2 mm diameter and 39.3 mm length, combined with a 160 g weight, make it easy to carry as an everyday lens.
