Filters - UV or not UV?
This last plot makes the order of UV absorbing effectiveness quite clear
● The Tiffen Haze-1 is best. It's a neutral filter so color balance is unaffected.
● Next is the Tiffen 812. Good UV blocking if you also want a warming filter
● The Hoya 81B is very similar to the Tiffen 812.
● The Hoya UV filter comes next, neutral, but with 2 stops of UV blocking.
● The B+W KR1.5 gives about 1.5 stops of UV blocking with slight warming.
● The Tiffen polarizer gives less than a stop of UV blocking, but that's not why you use a polarizer!
● The B+W and Hoya 1B aren't very good UV blockers. The 1B is slightly warming
● The three "generics" and the Tiffen UV protector are pretty useless for blocking UV, though they may make
fine, neutral, lens protectors.
My Pick
What I actually use when I need a UV filter or a protective filter is a Tiffen 812. Usually, for the type of work I do,
a warmer image isn't a problem, indeed it's often desirable. I also like to minimize the number of filters I carry so
my 812 serves three functions. It blocks UV, it protects the lens and it's a warming filter. Some people use an 81B
for this, but I slightly prefer the color shift of the 812. Not everyone wants a warming filter, so the clear winner for a
neutral filter that really bocks UV is the Tiffen Haze-1, though the Hoya UV should also be pretty effective.
