Exclusive CPS offer: £175 cashback on the Control Ring Mount Adapter EF-EOS R

Canon Ambassador Brent Stirton used the Canon EOS R with his existing EF 70-200mm f/2.8L IS II USM lens on location in Namibia, using the Control Ring Mount Adapter EF-EOS R.

From Friday 14 December 2018 to Thursday 10 January 2019, Canon Professional Services (CPS) members who buy a Canon EOS R can claim £175 cashback when purchasing a Control Ring Mount Adapter EF-EOS R – an offer extended to those who have already bought an EOS R, Control Ring Adapter or both.

Canon’s EOS R is a groundbreaking full-frame mirrorless camera that sets new standards with its full-frame 30.3MP sensor, ISO performance and Dual Pixel CMOS AF. Building on over three decades of continuous EOS innovation, the EOS R System is based around a pioneering lens mount that offers greater creative possibilities. It is an uncompromising balance of optical, mechanical and electronic engineering excellence, enabling innovative full-frame lens designs, faster autofocus and high-speed communication between the camera and lens. The all-new RF lens range delivers stunning performance and responsiveness for both stills and video.

If you already own EF and EF-S lenses, however, a range of easy-to-use EF-EOS R Mount Adapters makes it simple to use your existing lenses with an EOS R camera with no loss of quality or performance. The adapters are built to withstand professional use, with metal mounts on the front and back. They are also weather-sealed against dust and moisture, so you can keep shooting even in tough conditions.

The Control Ring Mount Adapter EF-EOS R is one of three adapters designed to enable you to use your existing EF and EF-S lenses with the EOS R mount, with incredibly high performance.

The Control Ring Mount Adapter EF-EOS R, in addition to making it possible to use EF and EF-S lenses with an EOS R camera seamlessly, adds a Lens Control Ring. This ring is customisable and easy to find without taking your eye from the viewfinder, giving you tactile manual control over settings such as aperture, shutter speed, ISO sensitivity or exposure compensation. In practice, you gain even more flexibility from your existing lenses.
