The Canon RF 28-70mm f/2L USM Lens with RF lens mount is the worlds first standard zoom lens with an f/2 aperture. It offers the kind of image quality you’d expect from an L-series prime lens, and adds a large f2 maximum aperture for more creative control and stunning bokeh. Its versatile focal length makes it ideal for capturing landscapes, weddings and portraits.
The new RF mount has been built on the strengths of the existing EF mount and is the result of detailed research by Canon engineers, who have designed an impressive optical system with a flange back distance of 20mm and a wide 54mm diameter lens mount – allowing for faster and lighter lenses with higher performing optics. The new mount’s 12-pin connection enables enhanced communication and power transmission between the lens and camera body, further enhancing lens design options, resulting in higher image quality and enhanced usability.
