Canon RF 16mm f/2.8 STM Lens

Canon RF 16mm f/2.8 STM Lens
Ultra-Wide Compact Prime – Expansive 108° Rectilinear Angle of View, Bright f/2.8 Maximum Aperture, Precision Aspherical Element, Super Spectra Multi-Coating, Smooth and Silent STM Stepping Autofocus Motor, Close 5.1″ Minimum Focusing Distance (0.26x Maximum Magnification), Dual-Function Focus/Control Ring, Rounded 7-Blade Diaphragm, Native Canon RF Mount (Excellent Condition)

The Canon RF 16mm f/2.8 STM is an ultra-compact, lightweight rectilinear wide-angle prime lens engineered to bring expansive optical perspectives to the Canon full-frame mirrorless RF-mount ecosystem. Designed for landscape photographers, interior architectural shooters, astrophotographers, travel documentarians, and handheld vloggers, this sleek prime pairs an expansive 108-degree field of view with a fast f/2.8 maximum aperture in a chassis that weighs mere ounces. The broad rectilinear field of view captures tight indoor spaces, sweeping outdoor vistas, and broad starry night skies with straight lines and true spatial rendering.

Its optical formula incorporates one precision aspherical element to limit distortion, minimize spherical aberrations, and deliver edge-to-edge sharpness and clarity across the frame. Individual elements are treated with Canon’s Super Spectra Coating to suppress internal reflections, surface glare, and ghosting, maintaining crisp contrast and accurate color fidelity even in difficult backlit environments or high-glare daytime conditions. Driven by a fast, quiet STM stepping motor, the lens provides rapid focus acquisition for still photography alongside smooth, near-silent tracking for cinematic video capture. Featuring an intimate 5.1-inch minimum focusing distance paired with a 0.26x maximum magnification, it produces close-up wide-angle compositions that blend dramatic foreground detail with deep background context. A knurled barrel ring doubles as a manual focus control and a configurable Control Ring for setting ISO, aperture, or exposure compensation on the fly, while a rounded 7-blade diaphragm produces smooth circular background roll-off.Canon RF 16mm f/2.8 STM Lens

KEY FEATURES & PERFORMANCE HIGHLIGHTS

16mm Rectilinear Ultra-Wide Perspective: Captures an expansive 108° field of view without fisheye curvature, perfect for interior architecture, real estate, landscapes, and travel.

Bright f/2.8 Maximum Aperture: Excels in low-light environments, facilitates night sky astrophotography, and keeps the overall physical profile compact and portable.

Compact & Portable Build: Ultra-lightweight footprint pairs easily with compact full-frame bodies, making it a reliable solution for gimbal setups and walkaround vlogging.

Precision Aspherical Element: Mitigates optical distortion and spherical aberrations to produce crisp edge-to-edge resolution and faithful subject reproduction.

Super Spectra Multi-Coating: Controls flare and ghosting when shooting toward bright sun, practical lamps, or high-contrast backlighting.

Quiet & Smooth STM Autofocus: Stepping motor delivers fast autofocus for action stills and silent, continuous focus tracking during video recording.

Close-Focusing Wide-Angle Macro: Focuses down to 5.1 inches with a 0.26x magnification ratio, creating dynamic perspectives with exaggerated foreground depth.

Configurable Dual-Function Ring: Functions as a manual focus ring or a programmable camera control ring for on-the-fly exposure adjustments.

Rounded 7-Blade Diaphragm: Delivers pleasing, circular background bokeh when isolating subjects close to the front element.
