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 RF-mount mirrorless digital cameras. 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.
