Connect your EOS R System to the wider world of EF and EF-S lenses
EF-S lenses are designed for APS-C sensor EOS DSLRs, but they can also be used on EOS R System cameras via adapter. The camera will automatically produce cropped images that match the smaller image circle of EF-S optics.
EOS R 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.
Expect your lenses to behave in the same way as they do on EOS DSLRs, turning in the same great performance with the same high quality.
Canon engineers developed the EOS R System adapters to maintain compatibility, quality and performance when connecting the EOS R to existing EF and EF-S lenses.
The Lens Control Ring can be programmed via the camera’s menu to adjust various settings such as aperture, shutter speed, ISO sensitivity and exposure compensation.
It’s easy to find the Lens Control Ring without taking the camera away from your eye. Gentle clicks give a tactile feedback in thirds or halves of a stop (and can be removed via a special Canon service for filmmakers wanting smoother operation).
Drop-In Filter Mount Adapter EF-EOS R takes the functionality of Mount Adapter EF-EOS R and adds the ability to use drop-in filters, removing the need to fit filters on the front of a lens, especially useful for wide-angles with a large front lens element. It’s available with either a variable neutral density (V-ND) filter2 or circular polarising (C-PL) filter, and a clear (CL) filter is also available for shooting without filter effects.
Neutral density filters help control the amount of light entering the camera which is useful for filmmakers looking to shoot with wide aperture/slow shutter speed combinations in bright light. It also lets landscape photographers use slower shutter speeds to blur movement in skies and water2.
Polarising filters cut through glare and haze and reduce the amount of light reflecting from glass surfaces. The filters also boost colour saturation and help add impact to colourful scenes.
Building over three decades of continuous EOS innovation, the EOS R System is based around a pioneering lens mount which offers greater creative opportunities and even more intuitive ways of capturing every moment.
