About this product

The Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter A is a compact accessory that enables EF and EF-S lenses to be used with Canon EOS R mirrorless cameras. It features a built-in drop-in slot for a variable ND filter, allowing photographers to adjust exposure from ND3 to ND500 (equivalent to 1.5 to 9 f-stops) without changing filters. This adapter ensures a secure, dust- and water-resistant connection with metal mounts on both ends for durability. Its design matches the appearance of EF lenses, and it can be wiped clean for maintenance. The adapter enhances creative control in variable lighting conditions.
