Canon EF 50mm f/1.8 STM Standard Lens: Capture important moments in your life with this standard lens, which works with your compatible Canon DSLR EF-mount camera. A circular aperture with 7 blades helps you add creative background blur.

Some items like your keys or wallet you just take everywhere you go because you just never know. For anyone with an EOS R series camera, add the RF50mm F1.8 STM lens to that list. As part of the EOS R System, it’s nice and compact thanks to its RF mount so you can shoot – and get a great shot – anywhere and anytime. Size isn’t all though. As a fixed focal length lens, it lets you be creative with composition and can be used for a wide range of scenes from snapshots to portraits, landscapes to low-light situations and more. Those images will stand out, too, just like you intend whether on social media, or when sharing or printing, thanks to impressive optical features like a PMo aspherical lens to suppress aberrations, Super Spectra coating to reduce flaring and ghosting, and a large f/1.8 aperture for low-light shooting and beautiful bokeh. Pick it up and use it one time and you’ll see for yourself, and you won’t be able to leave the house without it.

The Canon EF 50mm f/1.8 STM Lens is a compact and versatile normal-length prime ideal for everyday photography, offering a bright f/1.8 aperture that enhances low-light performance and allows for precise depth-of-field control. Designed for full-frame Canon EF-mount DSLRs, it also functions effectively on APS-C models with an 80mm equivalent focal length. Its optical design features Super Spectra coating to reduce flare and ghosting, ensuring strong contrast and accurate color in backlit or harsh lighting. The lens incorporates a smooth, near-silent STM stepping motor for fast autofocus, supported by advanced algorithms and a high-speed CPU, along with full-time manual focus override. A durable metal mount, repositioned focusing ring for compactness, and a rounded seven-blade diaphragm that produces pleasing bokeh round out this well-balanced and capable lens.

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.
