Comments about Vivitar Vivitar Multi-Coated Circular Polarizer (CPL) Glass Filter, 58mm:
I previously owned a Hoya circular polarizer and replaced it with this Vivitar after the Hoya got badly scratched during an outdoor backpacking trip. The Vivitar filter not only produces good quality images, but it cleaned up as good as new after a 15-day river expedition where it was was subjected to liberal doses of blowing sand and even some rain sprinkles.
