Roger Hicks, who tests gear and writes about it for a living (Shutterbug mag
and many books), says he's never noticed a nickel's worth of difference
between the major brands of filters. In his tests even the Cokins didn't
harm resolution. (Excluding those types of filters that by their nature
interfere with resolution - softening, etc.)
I don't doubt that certain UV/haze/skylight filters may prove optically
superior to others, but when it comes down to nths of a degree, it's hardly
significant for most photography. In my experience the major difference has
been in filter ring quality - more money buys a better quality ring that
won't jam in the threads, and glass that fits the ring properly rather than
loosening up where it's vulnerable to chipping.
Anyone out there ever had or seen a Rolev filter? You know what I'm talking
about. Plastic rings that warp or crap aluminum that jams, ill-fitting
glass, etc.
Personally, I thought the line of filters Vivitar used to market were pretty
good. Still have several, altho' in odd sizes - 46mm, 48mm.

IMHO Hoya runs a close third behind Heliopan and B+W. I've had a number of
their filters and never a complaint about them, especially the HMC, and the
Oly L39 (??) UV has been very good.
Always wondered if Hoya ever made a thin ring with their own name on it.

BTW, Heliopan has switched over completely to thin rings. YMMV as there is
still old stock out at the retailers. Not quite as thin as the Oly, but
very close.
