Would any of you guys know of existing accessories from the old line of canon videocameras that should be kept since they will also work with the new a1? Im thinking of stuff such as wide angle lenses and underwater housings. I havent found a site giving info on the size specs of the a1. Should gl2 accessories work? Is the 16:9 chip going to see vignettes thru my gl2 canon wide angle screw-on?
