Canon Drop-in Clear Filter A for EF-EOS R Drop-In Filter Mount Adapter

Designed for use with the Canon Drop-In Filter Mount Adapter EF-EOS R, this Drop-In Clear Filter A is a simple clear protective filter used to guard the interior of the camera body and rear element of the lens when the lens adapter is in use. It is primarily used when the Drop-In Filter Mount Adapter is in place, but no filter effects are desired.
