Ok so I went to the camera store looking for a polarizer but 1) this is my first filter so dont have complete understanding of the options other than brand, filter size, MRC, slim/not, and Cir vs Linear. 2) I'm in korea, dont speak any korean. In anycase I found a box with Hoya HD Cir-Pl printed on the front and on the back, HD coating 8 layer anti reflec... Water & Oil repell.... HD Frame....
but..on the filter itself, all it says is: Hoya HD Cir-PL 77mm made in Japan.
So my question is, how do I know if i got what I paid for and someone didnt just swap out a cheaper filter and put it in a nice box. Particuarlly I'm wondering if MRC is printed on the filter or not. The reason I ask is because I was first shown a B&W slim polarizer but MRC was not printed on the box let alone the filter. When I had my girlfriend ask the sales person, they said thats how it comes in the box. I decided on the hoya because it was 100,000 won roughly $90 vs the 180,000 won for the B&W.
To summarize, does B&W filters typcially not have anything but "slim polarizer" printed on them, and for Hoya, does the filter only say HD Cir-PL and nothing about the MRC?
