Canon EF-EOS R Mount Adaptor with Drop-in Variable ND Filter

Extending the range of compatible lenses, this 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 select A-type drop-in filters, and includes a variable neutral density filter for greater control over your exposure settings.

The adapter's design extends the ability to use filters with unique lenses that cannot accept filters on the front, and and it also retains full autofocus and image stabilization capabilities of the mounted lens. It is also dust- and water-resistant, making it suitable for use in harsh weather conditions.

Engineering excellence

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 standard Mount Adapter EF-EOS R allows EF-S and EF lenses to be used on EOS R cameras seamlessly. Photographers who already have a collection of EF-S or EF optics can invest in the EOS R System confidently, knowing their existing lenses will work as expected.

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) filter² or circular polarising (C-PL) filter, and a clear (CL) filter is also available for shooting without filter effects.
