The next MagFilter to be released from Carry Speed is the MagFilter Threaded Ring Adapter. There is no glass on this MagFilter Threaded Adapter Ring. This adapter allows you to use the filters of your choice with your high end compact camera like the Sony RX100.
Right now three different adapters (choose one) are designed to support 52mm, 55mm, or 58mm filters such as a Polarizer or ND Filter. The product has been announced, and should be available soon from http://CarrySpeed.com.
