The JJC RN-DC58D Filter Adapter for CANON PowerShot G15. It screws onto the face of the G15, around the lens, and provides a 58mm filter thread in order to attach filters. The filter adapter adjusts with the lens as the zoom extends and retracts. In this way, vignetting (the darkening of the corners in the image)is eliminated. 58mm filters, such as a circular polarising, neutral density and
skylight can be used for specific effects.
