Marketing Information: 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.
