Extending the range of compatible lenses, the Canon Drop-In Filter Mount Adapter EF-EOS R is a unique lens adapter designed for attaching any EF or EF-S-mount lens to the EOS R mirrorless digital camera. This sophisticated adapter affords compatibility with drop-in circular polarizer and variable ND filters, extending the ability to use filters with unique lenses that cannot accept filters on the front. It also retains full autofocus and image stabilization capabilities and contains no optical components, thereby maintaining the original optical quality of the mounted lens.
