Bring your EF-S lenses to the EOS R System
EF-S lenses are designed for APS-C sensor EOS DSLRs, but they can also be used on EOS R cameras via adapter. The camera will automatically produce cropped 11.6-megapixel images that match the smaller image circle of EF-S optics.

Built to last
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.
Designed to perform
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.

Control Ring Mount Adapter EF-EOS R
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.
Tactile, intuitive handling
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
Adapter V-ND: Variable neutral density filter
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 water.
Adapter C-PL: Circular polarising filter
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.
CL-Filter for Drop-In Filter Mount Adapter EF-EOS R
A clear filter, for users who have bought the drop-in filter adapter but who do not wish to have any filter effects.
PL-Filter for Drop-In Filter Mount Adapter EF-EOS R
A circular polarising filter which boosts colour, contrast and saturation, and controls unwanted reflections.
ND-Filter for Drop-In Filter Mount Adapter EF-EOS R
