b & w UV filter differences?

[muchachotron]

hi everybody. i'm about to buy a UV and a polarizer filter, and i'm just wondering what the differences are between these b+w UV filters:

B+W 72 mm UV-415 UV-Blocking Glass Filter ($94.95)

B+W 72mm UV Haze 010 (MRC) Multi-Resistant Coating Glass Filter ($62.95)

B+W 72mm UV Haze 010 Glass Filter ($46.95)

thats not a dramatic price difference, but is there any reason that the multi-coated one is less expensive than the UV-415 model? i've seen in at least one thread on this forum that dv cameras aren't even affected by UV interference, so should i just get the cheapest b+w UV filter for protection and maybe whatever minimal image enhancement it would provide? would the glass in the UV-415 filter be better than the cheaper ones?

i assume that i should get a multi-coated linear polarizer, since it's only 15 bucks more than the non-coated one.


also, another related question: if i stack both non-slim filters (the UV and then the Polarizer) on top of each other, will i get vignetting? would it make sense to get a slim polarizer to cut down on the length of the filter stack?

You don't need both a UV and a polarizer. Just go with polarizer if you're going to be doing lots of outside work.

If you are going to be putting on the polarizer only when you need it, then go with a clear filter for lense protection.

I think that UV-415 is what is known as a "strong" uv, intended for work on the ocean or high elevation, where the color temp rises well above the normal 5500.

Digital sensors are not UV sensitive, thus no UV filtration is ever needed.

Color temperature is taken care by white balancing.

I got the 010 for my camera, btw, B+W is the only way to go. I also got a polarizing filter, they do
different things for different situations. Advice was given here by a professional photographer to use
only one filter at any given time because of light loss.
