I'm looking for a budget fisheye with 43mm threads to use with a Vixia camcorder. Any good recommendations? My old Kenko .43x fisheye has served me well throughout the years, but I'd prefer a solution that doesn't require adapter rings (the Kenko has 37mm threads). It looks like the Opteka OPT-SC43FE is the main option, however, at .3x, I don't think it will be fishy enough for my tastes. Any help would be greatly appreciated!
