Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter

Selling my Canon drop-in filter mount adapter. This is the one that lets you use EF lenses on the newer RF mirrorless bodies while also having a variable ND filter built right in. Super handy for video or shooting in bright light without needing to swap filters on every lens. It's in good shape and comes with the rear cap. Works perfectly with all my L series glass.
