No, polarizers are very difficult to build to cover the whole visible spectrum as they are essentially a grating filter. And because they aren't perfect they can't cancel each other out 100%, so generally depending on the filter types/quality you end up with deep purples through to murky browns when two filters are out of phase. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
