Super Wider Semi Fish-Eye 0.42x (52mm)The Super Wider Semi Fish Eye screws into the front of your camera lens and provides a distorted, fisheye style wide angle image. This is a "fun" lens, but you should be aware that image quality is definitely marginal (as it is with nearly all fisheye adapters). Thread fitting is the adaptable Series 7; a 52mm lens thread adapter is included.
