Fisheye Lens For Canon Camera

Jenny asks…What is a good Fish eye for the Canon Vixia HF20?I just got my camera and was wondering what great fish eye i should use and does it need a filter for it?mr.eos answers:0.21x High Definition Fish-Eye Lens (37mm) does not live up the label of being a fisheye adapter. On my Canon Vixia HF20 it provides a wider angle of view (about 80 degrees) but it is far from providing a fisheye effect with a 180 degree field of view. It also only works when the camera is set to its widest angle,
