I have a 500 4.5, and well bad luck kinda stuck today. and some good. got some great photos but when I got close to going home I noticed my drop in filter holder and the pilarizer that was in it was gone. I looked and looked but could not find it. I searched online and could not find anyone that sells them. Does anyone know where I can get a holder from. and also can you still shoot without the holder in it? thanks
