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.

Lens Magnification Factor:	0.18x
Lens Magnification Factor: This is the magnifying factor of a lens. Macro lenses will often be described by their “magnification factor”. A lens with a 1:1 magnification factor produces a projected image on the sensor which is the same as the subject. View All Attribute Definitions
Elements / Groups:	19 / 13
Elements / Groups: The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs. View All Attribute Definitions
