The Canon Drop-In Clear Filter A is a filter that is designed to be used with the Canon Drop-In Filter Mount Adapter EF-EOS R. Because this filter is clear, it is used as a protective filter so the interior of the camera body and the rear element of the lens are guarded while the lens adapter is in use. Use this filter when you do not need any filter effects.Â
