I am planning to buy a CPL. Which one is better? Of course, if the quality is similar, I would get a cheaper one.

B+W CPL
Hoya Super HMC CPL
Kenko PRO1 CPL

I would choose multicoated over uncoated anytime. For HOYA, buy HMC or Pro1 if you need the front thread for lens cap. Buy HMC Super, Ultra (HMC) or Pro1 (HMC Super) if you need super thin mount. Buy the regular uncoated blue label if you planned to buy B+W regular (also uncoated but much more expensive and not worth it). As far as quality goes, I have done some tests with my B+W & HOYA CPLs, all results I got (slides & digital) are identical in every way. Surprise!

Do Kenko PRO1 and Hoya PRO1 have front thread?
