So I've been looking for a B&W MRC UV filter for my Canon 50 1.8 but I can't seem to find one on HVStar. I can find the non MRC ones, but not the MRC, am I just looking in the wrong place? Can anyone seem to find it on their site for me?
Also, what is the difference between brass and alloy filters? Is one preferred over the other? I mean, it's going on once, and staying there, so does it really matter?
That's the 2C (double-coated), not MRC (multi-coated). Not bad, but not as good at minimizing flare or as easy to clean. Why do you want/need a filter, anyway? Use your lens hood.
