Canon RF 28-70mm f2.8 IS STM

The Everyday Do-Everything Lens

Blending a fast aperture, compact size, and versatile wide-to-short telephoto zoom range, the Canon RF 28-70mm f/2.8 IS STM Lens can be an everyday do-it-all lens for all types of content creators. The 28-70mm zoom range and fast f/2.8 aperture make this lens well suited to everything from landscapes to portraits and everything in between. The lens also boasts L-series quality optics while keeping to a smaller form factor-and a relatively affordable price point for the performance and features. 

Fast and Small

The RF 28-70mm differs from its L-series counterpart (the RF 24-70mm f/2.8 L) by maintaining a much smaller and lighter form factor. It does this through an advanced optical design and a more conservative, but still very capable, 28mm wide-angle starting point. When not in use, the lens can collapse into itself, resulting in an even greater space savings in a bag or when slung over a shoulder. 

The relatively fast f/2.8 constant maximum aperture allows this lens key advantages over similarly sized options that opt for a more conventional f/4 aperture by enabling the creation of images with a shallower depth of field. Portraiture and low-light shooting will benefit from the more pleasing bokeh and increased light-gathering capabilities, respectively. 

L-Series Quality Optics

• Canon has placed the optical performance of the RF 28-70mm at the same level as their famed L-series lenses. This is no small feat, especially for a lens that also manages to maintain a relatively small form factor. The advanced optical design of the lens helps ensure detailed imagery is captured throughout the zoom range and even when shooting wide open.
• 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. 

Fast Autofocus and Built-In Stabilization

• Make the most of your lens' high-quality optics by using the RF 28-70mm's fast stepper (STM) autofocus system and Optical Image Stabilizer to ensure tack-sharp imagery. These two features will help lock onto your subjects and make sure that camera shake is controlled.
• 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.

Lightweight and Compact Design

• Key to the RF 28-70mm's success is the physical construction. It is small, lightweight, and durable. A weather-sealed construction, like L-series glass, helps ensure this lens is capable of being used rain or shine. This makes it a reliable choice for photographers and videographers.
• 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.
