Sony VFA-305R1 Overview
The Sony Filter Adapter Kit for RX0, DSC-RX0M2 Cameras includes a 30.5mm filter adapter, a multicoated protective filter, and a lens hood. These components reduce the amount of undesired light entering the RX0M2/RX0 Camera's lens.
You might consider leaving the MC filter (UV filter) attached to your camera at all times, as it both protects the camera's lens from scratches while reducing ultraviolet light. The lens hood helps eliminate unwanted reflections and glare, and the filter holder lets you attach 30.5mm filters to achieve various effects.
