hi, hope u guys can help me with this. i have just brought a B+W circular polariser from ebay, and i was told that it was an MRC version which was suppose to be multi-coated. i suspect that the one sent to me was a non-MRC version. How am i suppose to verify whether is it a MRC or non-MRC from the filter itself. does the filter ring bears the word MRC for multi-coated verision i felt cheated..please help

confused

I have only a skylight filter to check this: it has "MRC" printed on the cardboard box and "MC" on the filter itself. The non-MRC filters lack this code.

Hold the filter under a light and vary the angle of the filter to the light. The reflections of the light on the glass should have a color tint from the multicoating.

I believe that www.2filter.com has a description of how to see if the filter is MRC.

Basically, uncoated will reflect a light as white, mono-coated as a single color, and multi-coated as many different colors...
