CANON FADC67A Filter Adapter

The Canon Filter Adapter FA-DC67A for the PowerShot SX30 IS, SX40 HS, SX50 HS, SX60 HS, and SX70 HS is used to mount 67mm filters to the lens barrels of the cameras. 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.
