I am looking for a slim CPL filter (77mm) with front thread for my UWA lens for my coming New York trip. Apart from Hoya HD which is current out of stock in most places, any anyone advice me is what other brand slim CPL that comes with a front thread? I know B+W doesn't comes with front thread. I also consider Nikon but don't know where to buy..
I prefer some better quality ones which give lesser f-stop reduction...Tks!
