If you compared the Hoya UV(0) -1st, and the B+W UV MRC -3rd.
The B+W scores poorly with a 5/10 in the UV transmission test <390nm (as in, it's supposed to cut it out). the Hoya gets a 10/10.
I guess the UV filter is important for film but I didnt think it was quite so important for a CMOS Bayer sensor as they already have a UV filter. I am not saying the UV filter does nothing on a digital sensor just that the CMOS is much less sensitive than film.
In every other test the B+W slightly betters or equals the Hoya so in the end it is a 3 point difference.
The B+W is more expensive of course as they note.
The Tiffen really does seem to be a dud though, jeez
.
BTW I am not biased to either B&W or Hoya. As long as you pick a decent coated version and one that physically fits from either brand you cant really go wrong.
I have only 2 UV filters a Hoya UV(0) 52mm bought in Aust for the kit lens and a 49mm B+W MRC for Ltd lenses bought from the US so I paid about the same price for both.
I don't really use either of them.
I do like that the B+W is brass and quite solid build. The Hoya is Aluminium.
That reminds me, I have a 3rd UV filter. Its a Hoya 49mm and it's been jammed on a ??? lens on my old film Pentax since the early 90's. Perhaps thats why I like the brass ones for my metal lenses.
My 3 C-pol are all B+W and the few ND's are a mix of Hoya and B&W
