Re: Polarizer

The depends on which "model" you mean. The traditional HOYA filters have a 
piece of metal wire to hold the glass in place. I have never had any problem 
with this design, and much preferred it because they are thinner. Some of 
the multicoated CPLs have retaining ring which is the same as traditional 
B+W. The truth is, both got loosen themselves. In fact, my B+W loosen itself 
in no time as soon as I opened the box. I had to tighten it and applied a 
little threadlock. As to the brass mount, I have found it heavy and too 
heavy to rotate (I prefer lighter damping grease).

there are significant differences in the build quality, in my
experience. For instance, I had a 67mm Hoya CPL and one day the glass
just fell right out. Fortunately it was into my bag, not onto the
pavement. Nothing like that ever happened to me with B+W filters.
Or Contax filters, come to that, and they are supposed to be Hoya glass.
