Canon RF 28mm f/2.8 STM Lens

Pancake Wide-Angle for Full-Frame RF

Compact 28mm prime designed for full-frame Canon RF-mount cameras, offering a classic wide field of view (~75°) and providing coverage similar to approximately 45mm on APS-C bodies, making it a flexible everyday option for both stills and video work.

Bright f/2.8 Aperture

A f/2.8 maximum aperture supports shooting in available light and provides attractive subject separation and depth-of-field control, all while contributing to the lens’s remarkably slim, pocketable form factor.

Gear-Type STM Autofocus Motor

A gear-type STM (Stepping Motor) delivers fast, quiet, and smooth AF, making this lens ideal for video creators and vloggers as well as photographers who value responsive and discreet autofocus in everyday shooting scenarios.

Three Aspherical Elements & SSC

Incorporates three aspherical elements within an 8-element, 6-group design to help minimize distortion and spherical aberrations, while a Super Spectra Coating reduces flare and ghosting, enhancing contrast and color accuracy in bright or backlit conditions.

Customizable Control Ring

A configurable Control Ring lets you adjust important exposure parameters—such as aperture, ISO, shutter speed, or exposure compensation—directly from the lens, streamlining operation for both photographers and filmmakers working quickly on location.

Close-Focusing Versatility

A minimum focusing distance of 9.1" (23 cm) and up to 0.17x magnification make this lens a creative choice for close-up shots of food, products, details, and lifestyle scenes while still preserving a wide, contextual background.

AF/MF Switch & Full-Time Manual Focus

A dedicated AF/MF switch and full-time manual focus capability allow precise control over focusing at any time, which is especially beneficial for video shooters and photographers who prefer fine-tuning focus manually after AF acquisition.

Rounded 7-Blade Diaphragm

A 7-blade rounded diaphragm contributes to smooth, pleasing bokeh and attractive out-of-focus highlights, elevating the look of portraits, street scenes, and video sequences with subtle background blur.

4.2 oz / 120 g

Measuring just about 24.7 mm in length and weighing only 120 g, this lens is one of the most compact options in the RF lineup, making it an outstanding choice for travel, everyday carry, and low-profile shooting where a small, discreet setup is preferred.

The 8-element, 6-group optical design with three aspherical elements ensures high sharpness and controlled distortion, while Super Spectra Coating helps maintain clarity, contrast, and accurate color reproduction when shooting in mixed or backlit conditions throughout the day.

The gear-type STM focus system is optimized for smooth, quiet operation, which is particularly beneficial for video creators, vloggers, and run-and-gun shooters who need responsive AF performance without introducing distracting motor noise into their audio tracks.

A customizable Control Ring on the lens barrel enables direct adjustment of exposure-related parameters, minimizing the need to dive into menus and letting you react quickly to changing light, whether you're shooting stills, recording video, or live streaming on the go.

With a minimum focusing distance of 9.1" (23 cm) and up to 0.17x magnification, the RF 28mm f/2.8 STM is well suited for close-range shots of products, food, details, and lifestyle scenes where you want to combine subject intimacy with environmental context in the frame.

The 7-blade rounded diaphragm delivers smooth, pleasant background blur and attractive out-of-focus highlights, helping to give portraits, street imagery, and video sequences a more polished, cinematic feel.

A front 55mm filter thread ensures compatibility with widely available ND, polarizing, and effect filters, while the separately available EW-55 threaded lens hood can be used to further reduce flare and physically protect the front element during active use.

On full-frame RF bodies, the RF 28mm f/2.8 STM provides a classic wide-angle perspective, while on APS-C cameras it offers a field of view similar to a 45mm “normal” lens, giving creators a highly flexible, single-lens solution for multiple shooting styles across the Canon RF ecosystem.
