Canon RF 50mm f/1.8 STM Lens

Full-Frame Normal Prime

Classic 50mm focal length on full-frame RF cameras delivers a natural, normal perspective that’s highly versatile for portraits, lifestyle, street, travel, and general purpose photography and video work.

Bright f/1.8 Maximum Aperture

A fast f/1.8 aperture helps in low-light environments and provides enhanced control over depth of field, making it easy to create subject-isolating images with soft, blurred backgrounds and pleasant bokeh.

Compact & Lightweight Design

Weighing just 160 g and measuring about 69 × 40 mm, this lens is small and unobtrusive, ideal for walkaround shooting, travel, and keeping your RF kit lightweight without sacrificing image quality or speed.

STM Stepping AF Motor

The STM stepping motor delivers fast, quiet, and smooth autofocus, making this lens a strong choice for both still shooting and video recording, with full-time manual focus override for precise, fine-tuned control when needed.

Aspherical Optics with SSC Coating

Incorporates one precision-molded aspherical element to suppress spherical aberrations and distortion, while Super Spectra Coating (SSC) reduces ghosting and flare to maintain high contrast and neutral color in strong or backlit conditions.

Customizable Control Ring

A configurable Control Ring allows you to assign key exposure parameters, such as aperture, ISO, or exposure compensation, directly to the lens for faster, more intuitive handling tailored to your workflow.

Rounded 7-Blade Diaphragm

A rounded seven-blade diaphragm helps produce smooth, pleasing bokeh and attractive rendering of out-of-focus areas, particularly at wider apertures like f/1.8, enhancing portraits and close-up shots.

Features one PMo aspherical element to help control spherical aberrations and distortion for improved sharpness and accurate subject rendering, while Super Spectra Coating (SSC) minimizes ghosting and flare, enhancing contrast and color accuracy in strong or backlit lighting conditions.

The 50mm focal length with a 46° angle of view delivers a natural look that closely matches human vision, making this lens a great choice for portraits, casual shooting, and storytelling with minimal perspective distortion.

A minimum focus distance of 30 cm (11.8") and 0.25x magnification support semi-close-up work, allowing you to capture details, food, products, and lifestyle scenes with a shallow depth of field and pleasing background blur.

The STM stepping motor is optimized for smooth and quiet focus transitions, making the lens suitable for modern RF video workflows, including vlogging, talking-head content, and cinematic B-roll that benefits from responsive yet unobtrusive autofocus behavior.

The integrated Control Ring can be customized within the camera menu to handle critical settings such as aperture, ISO, or exposure compensation, enabling quicker, more intuitive exposure control and a more tactile shooting experience tailored to your style.

Weighing only 160 g and measuring about 69 x 40 mm, this lens is ideal as a compact “always-on” option for RF bodies, balancing comfortably even on smaller cameras and encouraging you to bring your kit everywhere you go.

A 43mm front filter size supports compact, affordable ND, UV, and polarizing filters, making it easy to build a minimal yet effective filter setup for everyday photography and lightweight video rigs.
