The JJC RN-DC58C Filter Adapter for the Canon Powershot G1X is used to mount 58mm filters to the lens barrels of the camera. The advantage of this adapter is that it adjusts as you change the zoom angle of the lens.
In this way, vignetting (the darkening of the corners in the image) is eliminated. JJC RN-DC58C replaces CANON FA-DC58C. It is made of ABS plastic.
