IR/UV filters M8 from B+W

[RobertB]

For my CZ 28 zm biogon I need a IR/UV filter.

Looking at the webshop I see the leica's are around 100 till 150 euro.
But, B+W also sells IR/UV filters.

Do they also work, or does it has to be leica?

And, I think the CZ 28 has a filterthreat of 46mm. Is this correct?
And what is the difference between the:
B+W 486 UV-IR sper 46 E
and:
B+W DP 486 UV-IR sper 46 E

It say's DP, what does this stand for?


Lots of questions. Hope someone can help me with it.

1. Yes they work
2. 46mm is correct
3. "DP" stand for Digital Pro", and is described word for word on B&H, "B&W Digital Pro filters are characterized by a brushed chrome brass ring that will stylishly blend with today's modern digital cameras for both still and video formats." I'm assuming this is just a style variance and the glass is most likely no different.

B+W filters made in Germany, frame is brass made , Leica ir/cut filter made in Japan by Marumi, frame is aluminum, both will work with same result.

Okey, thats clear.
For me it will be the B+W's than at half the price.

Thanks
