Canon RF 28-70mm f/2.8 IS STM

Canon has announced the RF 28-70mm f/2.8 IS STM, which is the 50^th lens in the RF range. This constant aperture zoom lens is designed to be a good choice for those looking to capture higher-quality images without compromising on portability.

It is 92.2mm in length when retracted and weighs 490g, making it one of the lightest lenses on the market with this focal range and sensor coverage. The RF 28-70mm f/2.8 IS STM allows for adjustments to shutter speed, aperture, or ISO by using the Control/Focus ring.  

Canon has placed the optical performance of the RF 28-70mm at the same level as their famed L-series lenses. The advanced optical design of the lens is claimed to 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.

The RF 28-70mm’s utilizes a fast stepper (STM) autofocus system and Optical Image Stabilizer.

• 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.
