Canon RF 16mm f/2.8 STM Lens
Ultra-Wide Compact Prime for Full-Frame R-Series Mirrorless Cameras
The Canon RF 16mm f/2.8 STM is an ultra-wide-angle prime lens that beautifully blends an expansive field of view with an incredibly compact, pancake-style design. Engineered specifically for Canon’s full-frame R-system mirrorless camera bodies, this rectilinear prime delivers an expansive perspective without curving straight lines.

Boasting a bright f/2.8 maximum aperture and an ultra-lightweight footprint, it serves as an excellent everyday creative tool for broad landscapes, dramatic architectural interiors, astrophotography, and high-impact vlogging setups.

Rectilinear Ultra-Wide Perspective & Creative Close-Up Range
Expansive Ultra-Wide Horizon: Captures an ultra-wide field of view that is ideal for exaggerating the scale of tight indoor rooms, encompassing vast mountain ranges, or framing sweeping cityscapes in a single shot.

Unique 5.1-Inch Close-Focusing: Features an impressively close minimum focusing distance of just 5.1 inches (13 cm) paired with a maximum magnification of 0.26x. This lets you step directly up to a foreground subject for dramatic macro-style perspectives while maintaining a sweeping, wide-angle view of the background environment.

The Ultimate Portable Vlogging Companion: The featherlight design combined with the broad 16mm framing makes this optic an exceptional choice for content creators and vloggers, allowing for easy self-shooting at arm’s length while comfortably keeping the background in frame.

Precision Optical Layout & Custom Control Architecture
Aspherical Distortion Correction: Incorporates one specialized aspherical element within its optical layout to aggressively suppress field distortion, maintaining crisp resolution and accurate subject rendering across the entire frame.

Super Spectra Flare Suppression: Treated with Canon’s proven Super Spectra Coating to combat internal reflections, ghosting, and lens flare. This preserves rich tonal contrast and color fidelity when working under harsh, direct sunlight or strong backlit conditions.

Configurable Control Ring: Features a dual-purpose physical ring on the lens barrel. By toggling the integrated selector switch, the ring can be used for precise manual focus tracking or assigned to adjust critical exposure settings like aperture, ISO, and exposure compensation on the fly.

Smooth, Quiet STM Focus Drive
STM Stepping Motor Technology: Driven by a gear-type STM stepping motor that ensures fast, highly accurate focus tracking for still photography. It provides smooth, near-silent focus transitions during video capture to keep operational noise out of your microphone tracks.

Bright f/2.8 Aperture & Rounded Bokeh: The bright f/2.8 maximum aperture aids in low-light indoor or twilight shooting while contributing to a remarkably sleek lens profile. When shot wide open, a rounded seven-blade diaphragm yields a soft, pleasing bokeh quality.
