One of the most versatile focal lengths available, the EF 50mm f/1.8 STM Lens from Canon pairs this classic lens design with enhancements to the AF system and physical design that make it both faster and smaller. Utilizing an STM stepping motor, this lens is ideal for both still and video shooting due to its speedy and smooth operation. Further benefitting video shooters, the STM motor also supports the Movie Servo AF mode on select DSLRs for precise and near-silent focusing. An updated exterior design includes a metal lens mount and a re-located focusing ring in order to accommodate the compact overall form factor. The 50mm f/1.8 is a classic, tested lens design, and thanks to enhanced autofocus and a svelte profile, this lens is ideal for everyday shooting in a wide variety of conditions. The optical design of this lens incorporates optimized coatings that help to reduce flare and ghosting for increased contrast and color neutrality. The f/1.8 maximum aperture is effective for low-light shooting as well as for controlling your focus plane for selective focus shooting. Seven rounded diaphragm blades further enhance the look of out of focus regions in an image, making it well-suited to portraiture and creative environmental shooting.
