Hello Nikoners, I would like to buy one NIKON Polarising Filter for all my lenses. I have AF 35mm f/2 (52mmm), 85mm f/f1.8 (62mm) and I'm looking for 80-200mm f/2.8 (77mm). That means I need 77mm Polarising Filter or!? How can I use this filter with all my lenses? Is that the cheapest alternative? Thanks Samir Helsingborg Sweden
