7D owners who use a CPL

What brand are you using and what are your thoughts on it? I had a CPL that caused focus issues and I want to know what you have had good experiences with. Thanks!

Ive used B+W MRC Kaesemann (the non-kaesemann is just as good, just isnt sealed) with good results in the past. Ive since switched to a Lee system and use the Lee 4x4 CPL.

Which one did you have that gave you bad results? The one thing you have to remember is that CPL's reduce the amount of light you're getting by a few stops so what you're describing as focus issues could be motion blur/handshake blur. Of course, I have no way of knowing this for sure in your case - just throwing it out there.

I posted the issues in a thread 2 weeks ago... I was shooting at 1/2500 and faster.. But I did some tests after that using AF and it would still cause OOF images.

Thanks for you input on the B+W.

B+W..... no problems here, works great. spend the extra and get the mrc.

That could be the case, but I am also looking into Hoya and Tiffen
as well. B+W has 17 models in 67mm....

B+W MRC Kaesemann from B&H

B+W KSM Non Slim in that size, or get a 77mm and use a step up ring. Oh get it from Maxsaver. Much cheaper, and same thing.

B+W Kaesemann or Singh Ray Vari-n-Duo here; never had either of them give me any problems whatsoever.
