(From Canon lens literature) The Canon RF 28-70mm F2 L USM features a maximum aperture of f/2, offering unparalleled performance throughout its zoom range. With L series optics, it offers the flexibility and performance of a handful of fixed focal length lenses, delivering superlative performance from 28-70mm.

Designed to take advantage of everything the RF mount has to offer, RF lenses represent a new frontier in lens design for mirrorless cameras. With a large 54mm lens mount, large diameter elements to match and placement closer to the image plane, RF lenses provide brilliant image quality edge-to-edge with minimal light fallout, enabling new possibilities for enhanced optics and compact designs. A supercharged 12 pin communication system optimizes data transfer between camera and lens for sharp, stable and responsive performance in a wide variety of applications. Delivering features and performance engineered to astound, RF optics herald a new day in Canon's legacy of optical brilliance.

INNOVATIVE OPERABILITY

Control Ring
All RF lenses incorporate a control ring on the lens barrel that can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the front of the lens and effectively adding a third dial to the EOS R camera's main dial and quick control dial, the control ring has a tactile, easily distinguished surface and features a clicking mechanism that provides tangible feedback for confident use while looking through the viewfinder.

Lens Information Display
Another helpful feature, the EOS R camera can display lens information right in the viewfinder, making it easy to confirm the lens's focal length without looking away from the subject at hand.

Availability and Pricing
The Canon RF 28-70mm F2 L USM will all be available for purchase in December 2018 for an estimated retail price of US$2999.
