best circular polarizer?

Any suggestions?

I have a Hoya HD cir-pl for every lens I own. Love them.
I am always shooting near water and in harsh sun light. I use them a lot.

How serious are you about a good CP and how much you willing to spend. My choice was Kaesemann from Schneider. At this price I bought the largest size I needed for my lenses and step rings for the other lenses. I only own one.

B+W, Singh Ray, Heliopan, Hoya Pro 1. Buy a good one. I am a fan of Singh Ray and B+W. I've never used Hoya or Heliopan but I've heard good things.

Be careful. I bought a good one and it still would make my images slightly soft. Read reviews here and if you buy from Adorama there are usually tons of reviews.

I also suggest getting one to fit your largest lens and step up rings to fit it on your other lenses. I'm using a Hoya Pro1 CPL. - TF

I have a B+W and I'm very happy with it. Like others, I bought one to fit my largest lens, and use step up rings for my smaller lenses. Much less $ than buying multiples, and lighter to carry.

I did that for a while but still want to use my lens hood.
I am facing the sun to often to be without the hood.

Here's a pretty good review on the Hoya HD
