EOS R Compatibility with EF-S Lenses

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.

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

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) filter or circular polarising (C-PL) filter, and a clear (CL) filter is also available for shooting without filter effects.

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.
