The kit comes with 9 adapter rings for all sorts of lens sizes. You screw the adapter onto your lens, then the square piece screws onto the adapter and the filters slide into the square piece. The lens sizes the adapters fit are 49 mm, 52 mm, 55 mm, 58 mm, 62 mm, 67 mm, 72 mm, 77 mm and 82 mm. It matters more of the lens size than the camera you are using. Have fun with them!!
