mzd 9-18mm UWA -- circular polarizer question

??? Really? Why? Is there a source? Any help is appreciated.

Why is this the case? Forgive me as I'm no CP expert. Do you happen to have a source on that? Also, would today's linear polarizers be the same quality (and multi-coat) as a CP? I would think most of the R&D went in CPs over the last decade or so.

Thanks for any help.

This may be OT, but for µ4/3 you don't need a circular polarizing filter, a linear one will do. For 4/3 with a mirror, you'll need circular.

Can't answer the question though.

I refuse to wed myself to any of these vendors. I'm just having fun taking pictures,
and watching the technology develop.
