Received a SX50HS as a b'day gift. Still learning all the bells and whistles. Is it possible to find a third party UV filter holder manufacturer who builds an adaptor that will fit the lens screw, or is the screw a few straight grooves and really not a thread, and also accept a stepup or stepdown adaptor allowing me to use previous camera filters and WA lens? I understand the Canon UV adaptor has a maximum 67MM diameter and is not threaded inside or outside to accept any additional accessories. Thanks for your help!
