The EF-EOS R lens adapter for drop-in filters offers the same functionality as the EF-EOS R lens adapter, but with the added ability to attach drop-in filters. This means that the filter no longer needs to be mounted at the front of the lens, which is particularly advantageous when using wide-angle lenses with a large front element. Includes circular polarizer (drop-in filter). Polarizing filters not only reduce reflections on glass and non-metallic surfaces but also minimize haze. The filters enhance color saturation and create particularly vibrant scenes.
