Tom, >>>>>>>> ....Unfortunately, as far as I know, Nikon does not supply a lens cap for the 77 mm circular polarizer, which leaves it very >>>>>>>> I had the same problem with my Nikon's 52 mm cir-polarizer. The front screw diameter is 60 mm and I was not able to find any lens cap to fit this filter. Also, I didn't want to use the compatible metal lens hood HN-12 (?). So, I bought a step-up ring to the next standard screw size (60->62mm) and now I can use a normal, snap-type lens cap. Igor
