Cokin BZ100A Filterhalter Z Pro Serie

This type of Polariser and matching Filter System makes sense if you have more than a couple of favourite lenses. Have found that the optical quality is very good but then it should be for the price. You get what you pay for really! Think carefully before buying several separate screw on Polariser filters and see if you might be better off with this instead as if you have the matching holder and holder to lens adaptors this could well be a better option and optically it is probably superior. Would recommend.
