Canon RF 16-28mm f2.8 IS STM Lens

• Fast, Constant f/2.8 Aperture: Maintains a bright f/2.8 exposure value across the entire zoom range, making it exceptional for low-light environments, indoor video production, and astrophotography.

• Up to 5.5 Stops of Optical Image Stabilization: Built-in optical IS delivers rock-steady handheld shots, scaling up to an outstanding 8.0 stops of coordinated stabilization when paired with an EOS R camera body featuring In-Body Image Stabilization (IBIS).
• Leadscrew-Type Stepping Motor (STM): Features a high-thrust, rapid, and near-silent linear STM drive that provides ultra-smooth continuous autofocus tracking for both stills and cinematic filmmaking.
• Advanced Optical Formula: Comprises 16 elements in 13 groups, heavily packed with four Ultra-Low Dispersion (UD) glass elements and two aspherical elements to drastically lower chromatic distortions and edge-to-edge aberrations.
• Super Spectra Coating (SSC): Optimizes light transmission across individual glass elements to dramatically eliminate ghosting and lens flare when tracking backlit horizons.
• 9-Blade Circular Aperture Array: Produces beautifully soft, rounded out-of-focus highlights and a premium bokeh aesthetic for wide-angle portraiture or close-up subjects.
• Dual-Function Focus/Control Ring: Integrates a customizable physical ring on the front barrel that toggles natively between precise manual focusing and on-the-fly camera settings like ISO, exposure compensation, or aperture.
• Impressive Close-Focusing Macro: Focuses down to just 0.2 meters (7.9 inches) at the 28mm focal length with a maximum magnification factor of 0.26x, unlocking dynamic wide-angle macro perspectives.
• Retractable and Lightweight Chassis: Weighing a highly nimble 445 grams and measuring 91mm when retracted, it stands as an ultimate travel companion that balances flawlessly on smaller motorized gimbals.
• Robust Weather-Resistant Build: Extensively sealed at key components to resist moisture, dust, and raindrops, ensuring reliable field execution on location.
