I was looking for a new cpl and came across this Kenko. Does any one know what the "wide band" means? And how do you guys feel about the pro1 digital dmc line? I know the Kenko would be the same as the Hoya pro1 digital. I did a search and as always there are the mixed reviews of Hoya vs. B&W. I've heard some people say they like the pro1 digital dmc cpl's but have yet to see any thing bad about them.
