For those of you who looking to add filters to your Sony RX100 Carry Speed has come out with an ingenious way to adapt them to your camera. The Sony for example doesn’t have a traditional filter ring so the MagFilter uses magnetism to stick to the end of the little Zeiss lens. Carry Speed makes both an adapter ring for 52mm, 55mm, and 58mm (of course you can add step up or step down filters to these) and they have also made a circular polarizer lens that works in the same way.
