OVERVIEW
The Canon RF 28–70mm F/2 L USM Lens gives a fast performance in autofocus and exposure metering when mounted on Canon RF mount cameras. Its optical design of 19 elements in 13 groups includes Ultra-Low Dispersion elements to correct chromatic aberrations and maintains color neutrality. The ring-type Ultrasonic Motor delivers a fast yet accurate focusing performance. Also, the AF motor is internally housed to maintain the overall barrel length. You can adjust the aperture, ISO, and exposure compensation of the camera with the configurable dial. The rounded 9-blade diaphragm produces circular bokeh to enhance the shallow depth of field. With the weather-resistant design, the lens can work without any difficulty in inclement conditions.
