Calumet Filters?

[SillyGuy]

Hi all

How are Calumet UV, ND, and polarizer filters compared to other brands like Hoya, B+W, etc?

thx!

Since it's a house brand, they're re-badged someone else's. At a glance, the cases look like Hoya's, and the writeup sounds suspiciously like that Hoya uses for their HMC. If that's so, they'll be inferior to B+W MRC, Hoya S-HMC, Hoya DMC and Heliopan SH-PMC. Generally house brands are low or mid quality level.
