The FA-DC58D Filter Adapter for PowerShot G15 from Canon 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. 58mm filters, such as a circular polarising, neutral density and skylight can be used for specific effects.
