Constant f/2.8 Performance
Cinematic Subject Separation and Low-Light Power
The Canon RF16-28mm f/2.8 IS STM combines a wide 16-28mm focal range with a bright constant f/2.8 maximum aperture. This allows you to maintain consistent exposure settings across the entire zoom range while generating beautiful subject separation from the background.
The 9-blade circular aperture renders out-of-focus highlights with a smooth, cinematic blur. Furthermore, the large aperture lets in ample light, enabling faster shutter speeds and lower ISO settings when shooting astrophotography, indoor venues, or twilight landscapes.
Constant f/2.8
Maintain consistent exposure and depth of field whether shooting at 16mm or 28mm.

Portability Redefined
Soda-Can Portability at Only 445g
Traditional ultra-wide constant f/2.8 zooms are notoriously heavy and bulky. The RF16-28mm f/2.8 IS STM redefines expectations by fitting comfortably in your hand like a soda can, weighing approximately 445g and measuring about 91mm in length.
Being almost 30% shorter and nearly half the weight of the conventional RF15-35mm f/2.8L IS USM, it empowers creators to shoot all day without wrist fatigue, making it the ultimate travel and gimbals companion.
Compact Dimensions
Measures just 76.5 × 91.0mm when retracted, fitting effortlessly into compact camera bags.
Gimbal Friendly
Balanced weight distribution makes it exceptionally easy to stabilize on motorized gimbals.
L-Series Durability
Features dust and drip-resistant sealing comparable to professional L-series lenses.
Advanced Stabilisation
Up to 8 Stops of Coordinated Image Stabilisation
Equipped with a built-in Optical Image Stabilizer offering up to 5.5 stops of shutter speed compensation independently, the lens takes handheld stability even further when paired with compatible EOS R camera bodies featuring In-Body Image Stabilization (IBIS).
Through Coordinated Control IS, you gain up to 8 stops of image stabilisation. This technological synergy allows you to capture tack-sharp handheld long exposures in dim lighting conditions that would otherwise demand a tripod.
Handheld Freedom
Shoot steady twilight cityscapes and dimly lit interiors at slow shutter speeds completely handheld, opening up creative angles where tripods are impractical or prohibited.
Optics & Autofocus
Precision Glass and Cinematic Focus Transitions
The optical construction consists of 16 elements in 13 groups, featuring 4 UD (Ultra-low Dispersion) lenses that effectively correct chromatic aberrations. Additionally, a large-diameter replica aspherical lens and a GMo aspherical element minimize spherical aberrations and wide-angle distortion while keeping the barrel compact.
Leadscrew-Type STM
Delivers rapid, precise still photography focus and whisper-quiet operation for video recording.
