1A filter vs 1B filter?

[joe...@vnet.net]

Today I received a new 105mm Nikkor lens I ordered from J&R Music
World. When I ordered the lens I asked for a Skylight 1-A filter
which I planned to use mainly to protect the lens' front element.
When the shipment arrived, I noticed the filter, a Hoya, was a 1B
not a 1A. I compared the enclosed pamphlet's description of the
1B with a pamphlet which came with a Tiffen filter which describes
a 1A, and they sound identical. The Hoya pamphlet makes no mention
of a 1B and the Tiffen pamphlet makes no mention of a 1B! What's
going on here?!?!?

1A is supposed to be milder than 1B, and less pinkish.

All skylight filters suck. You ruin all the efforts of Nikon engineers
working very hard to give a neutral color in a Nikkor lens. The pink
color cast of a skylight filter will ruin that colour balance. Unless
you shoot with flash where a pink cast is desirable, do NOT use a
skylight filter !

Don't sweat it!. They are functionally equivalent.

So what's the alternative for lens protection then ? UV filter ?

I disagree. The neutral color is desirable as a starting point, but
nevertheless photographers use filters all the time to correct for lighting
balance problems (or for creative reasons). The sky filter is intended for
use in open outdoor shade, under a blue sky, etc., and it cuts haze a little
bit. The color balance change is virtually unnoticeable in prints, although I
understand it is quite apparent in slides.

This works.

Oh come on, this position is asinine unless it was posted as a joke.
Skylight filters correct for the deviating color temperature of high
altitudes and/or shade, where some films (notably Velvia) turn VERY blue.
(In fact, I don't find an 81A or B enough to counter Velvia's blue shift).

The color shift of the film in such situations also ruins the color
balance that the lens engineers have striven so hard to attain, so perhaps
we should take that out of the equation also. Yes, I think that is the
answer: ALL FILM SUCKS!! because all film will alter the color balance of
the lens. So please everyone, let's stop using film and thereby stop
insulting Nikon lens designers.

: people who like to use protective filters on lenses. I like to use 1A
: and UV filters that are multicoated and of good optical quality - check
: out filters made by Hoya and Nikon (they cost more, but are worth it IMHO).

From what I can find on the Hoya product line, I think they only make a
1B filter. I don't see a 1A in the regular part of the brochure (unless
it's tucked away in some chart somewhere).

Does anyone know if Nikon's designation of L1BC means they use a 1B
filter also?
