Canon RF 28-70mm f/2.8 IS STM Lens (Canon RF) Overview
• Two Ultra-low Dispersion (UD) elements are located at the front of the lens design, a configuration previously found only on L-series lenses, which correct chromatic aberration and reduce the weight of the front lens group.
• Two glass-molded aspherical elements suppress aberrations and help maintain a compact overall lens size.
• Super Spectra Coating (SSC) reduces backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting condition.
• Stepper (STM) autofocus motor is fast and silent for optimal operation during both still and video capture.
• Focus breathing is well controlled, resulting in smooth rack focuses during video recording.
• Optical Image Stabilizer is rated for up to 5.5 stops on its own or up to 7.5 stops when used in coordination with a compatible camera’s built-in stabilization system. This system will help reduce blur from camera shake when shooting handheld, even in dark shooting situations and with longer shutter speeds.
• Collapsible design keeps lens size even more compact when not in use.
• Customizable Control Ring and smooth manual focus ring allow for tactile operation of the lens.
• Weather-sealed construction enables operation in less-than-ideal weather conditions.
