Has anyone tried KENKO Zeta filters?

I was at my local camera shop looking for a new CPL filter and was recommended a new line a filters made by Kenko (THK). He says they're called Zeta and are supposed to be one level above the Kenko Pro1D. Supposedly it's of similar quality to the B+W MRC series of filters but at half the price.


Have any of you folks had experience with these filters? Any feedback would be greatly appreciated. Thanks!

As far as I am concerned if you are planing on using any filters please do yourself a favor and stay away from anything not made by B+W or Heliopan
These are by far the only two serious filters
Except for cokin and lee square filters

I personally like B+W

Good luck with you purchase.
