The Opteka 37mm 0.43x HD Full Fisheye Converter Lens uses multi-coated, low-dispersion glass to produce crisp, high-definition video images. Great for dramatic effects and very wide fields of view--think sports, think dream sequences, think HAL-9000 computers--this fisheye converter screws onto the front of your existing camcorder lens and bends a 180° view into a peephole-style circle. Since this is a conversion lens, you can use it through your camera's full zoom range.
