Canon RF 50mm f/1.8 STM Lens (Canon RF)

The Canon RF 50mm f/1.8 STM is a sleek, ultra-compact normal prime lens engineered for full-frame Canon RF-mount mirrorless camera bodies. Known as a classic “nifty fifty,” it delivers a natural field of view alongside a fast f/1.8 maximum aperture, making it an ideal carry-everywhere optic for low-light shooting, portraits, and everyday street photography. The refined optical design incorporates a precision-molded (PMo) aspherical element and Super Spectra coating to combat spherical aberrations, ghosting, and flare for sharp, high-contrast imagery. Equipped with a whisper-quiet STM stepping motor for smooth video and still autofocus, the lens also features a customizable lens Control Ring for quick adjustments to ISO, aperture, or exposure compensation.
