Canon RF 16-28mm f/2.8 IS STM Lens (Canon RF)

Canon RF 16-28mm f/2.8 IS STM Lens
Ultra-Compact Wide-Angle Zoom – Constant f/2.8 Aperture, Up to 8-Stop Coordinated IS & L-Series Level Weather Sealing

The Canon RF 16-28mm f/2.8 IS STM is an ultra-compact wide-angle zoom lens designed for Canon full-frame RF-mount mirrorless cameras. Engineered as the smallest and lightest RF zoom lens in its class, weighing approximately 1 lb, it combines exceptional mobility with a bright constant f/2.8 maximum aperture. This fast aperture delivers consistent low-light performance and pleasing depth-of-field isolation across the entire 16-28mm focal range, making it an ideal tool for travel, landscape, architecture, and vlogging workflows.

Built to match the optical quality and weather-resistant durability of Canon’s L-series lenses, the optical design incorporates four Ultra-Low Dispersion (UD) elements and two aspherical elements to eliminate chromatic aberrations and maintain edge-to-edge resolution. For handheld stability, integrated Optical Image Stabilization offers up to 5.5 stops of standalone shake correction and up to 8 stops when paired with camera bodies featuring In-Body Image Stabilization (IBIS). Powered by a leadscrew-type STM stepping motor, the lens provides rapid, quiet autofocus with minimal focus breathing during video recording.

Key Features & Production Versatility

Compact Constant f/2.8 Ultra-Wide Zoom: Lightweight 1 lb design offers a bright f/2.8 maximum aperture for consistent exposure and soft background blur.

Advanced Optical Design: Features 16 elements in 13 groups, including 4 UD elements and 2 aspherical elements to control distortion and color fringing.

Powerful Image Stabilization: Built-in optical stabilization provides 5.5 stops of shake correction, extending up to 8 stops with IBIS-equipped EOS R bodies.

Leadscrew-Type STM Autofocus: Delivers quick, near-silent AF tracking with suppressed focus breathing for smooth video transitions.

L-Series Level Durability: Weather-resistant sealing protects against dust and moisture in challenging outdoor environments.

Super Spectra Coating (SSC): Suppresses internal reflections, lens flare, and ghosting for accurate color and high contrast.

Close-Up Capability & 67mm Filter Thread: Focuses down to 7.9″ at 28mm (9.8″ at 16mm) and accepts standard 67mm front filters.
