The Canon RF 28-70mm f/2.8 IS STM Lens combines a fast aperture with a compact size and a versatile zoom range, making it an ideal all-purpose lens for various content creators. With its 28-70mm range and f/2.8 aperture, this lens excels in capturing everything from landscapes to portraits and more. It features L-series quality optics while maintaining a smaller design and a comparatively budget-friendly price for its 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 capable, 28mm wide-angle starting point. When not in use, the lens can collapse into itself, resulting in 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 creating images with a shallower depth of field. Portraiture and low-light shooting will benefit from the more pleasing bokeh and increased light-gathering capabilities.

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 corrects chromatic aberration and reduces the weight of the front lens group.
• Two glass-moulded 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.
