The Canon RF 16mm f/2.8 STM is a compact, full-frame ultra-wide-angle prime designed for Canon RF-mount mirrorless cameras. Combining a bright f/2.8 aperture with a lightweight, portable design, it’s ideal for interiors, architecture, landscapes, astrophotography, vlogging and content creation.

Its wide field of view lets you capture expansive scenes with ease, while the slim form factor makes it an everyday lens you can take anywhere.

Wide views in a compact lens

This rectilinear 16mm prime delivers a broad, natural-looking ultra-wide perspective that works for everything from sweeping landscapes to indoor photography. The f/2.8 maximum aperture supports available-light shooting and gives you greater control over depth of field, while also helping keep the lens small and lightweight.

Sharp, accurate optical performance

An aspherical element is used in the optical design to limit distortion and promote high levels of sharpness across the frame. To maintain strong contrast and colour fidelity, Super Spectra Coating is applied to reduce flare and ghosting, especially when working in strong or backlit conditions.

Smooth and quiet autofocus

The STM stepping motor delivers fast, smooth and near-silent autofocus, making this lens well suited to both still photography and video recording. Focus transitions are natural and controlled, supporting cinematic video and accurate stills shooting.

Get closer than you expect

With a minimum focusing distance of just 5.1 inches and a maximum magnification of 0.26x, this lens offers a unique approach to close-up wide-angle photography, allowing you to keep foreground subjects sharp while retaining depth and context in the background.

Built for intuitive control

A customisable control ring lets you adjust key exposure settings such as aperture, ISO or exposure compensation, giving you quick, tactile control while shooting. The rounded seven-blade diaphragm produces pleasing bokeh, adding smooth background rendering when working at wider apertures.

Minimum focusing distance of 5.1", along with a maximum magnification of 0.26x, makes this a unique option for close-up shooting while retaining great depth of field.
