Lens adapter EF-EOS R (for drop-in filter, incl. C-PL filter) offers the same functionality as the lens adapter EF-EOS R with the additional possibility to attach plug-in filters. Thus, the filter no longer has to be attached to the front of the lens - which is particularly advantageous when using wide-angle lenses with a large front lens. There is an adjustable neutral density filter (V-ND), a circular polarizer (C-PL) and a clear filter (CL) for recording without any filter effects.
