A little back round - I've been shooting for 30+ years and am updating some equipment in the digital range.
I have just purchased a Tokina 11-16 that has a 77mm lens.
In going through my dozens of older filters, I found 2 - 77mm Polarizers that I used with a Bronica lens.
Am I correct that the proper filter that I need for the 11-16 is a circular filter for that lens?
In looking a my 72mm polarizer, I see that it specifies C-PL.
Do all circular filters say so on the edge?
I can't remember why I have 2 of these filters, one is a Tiffen and the other is a Tokina.
If these don't work with any of my current equipment, I guess I should just try to sell them and buy something I can use.
