Lawrence Ripsher's Photo Journal: To UV Filter or Not to UV filter... (http://scaredofthedark.typepad.com/blog/2007/01/to_uv_filter_or.html)


I like the way this guy thinks and speaks.

He mentionss the Hoya Pro D1 filters but these are only multicoated.

I've always prefered the SMC stuff

In 1996 Hoya introduced the line of Super Multi-coated filters. Consisting of a Skylight, 1B, UV (0), ND 2X, ND4X, and a low profile circular polarizer, this line of filters has a 5+1 layering system on each side of the glass: 5 layers of anti-reflective coating and a transparent easy-clean top coat. This reduces light reflections off the filter surface to an average of just 0.3%. This is the lowest reflective rate on the market, from any filter manufacturer

That makes interesting reading.
