The Canon RF 28-70mm f/2 L USM is a professional full-frame zoom that pairs a useful everyday focal range with an unusually bright constant f/2 aperture. It’s built for photographers who want prime-like low-light performance and depth-of-field control without giving up the flexibility of a zoom.
Bright f/2 Zoom
The constant f/2 aperture stays available from 28mm through 70mm, making the lens well suited for low-light shooting, portraits, events, and situations where strong subject separation matters.
Optical Performance
Ultra-Low Dispersion elements help reduce color fringing and chromatic aberrations for cleaner detail and more accurate color across the zoom range.
Fast Autofocus
A ring-type USM motor, internal focusing design, and Canon’s focusing algorithms provide quick, precise, and quiet autofocus. Full-time manual focus override is also available whenever you want more direct control.
L-Series Build and Controls
A customizable Control Ring can be assigned to settings such as aperture, ISO, or exposure compensation for quicker adjustments while shooting. As an L-series lens, the RF 28-70mm f/2 also features dust- and moisture-resistant construction for added reliability in changing conditions.
