I try often like only a cheap product from before I put real money on the table. However, I expect then not much. Should I use the product frequently and enjoy it, but it out quickly or be too tight, but then I buy the more expensive. With polarizing filters which is complete nonsense !!! Who wants to have the effect described in the trade press or books, needs this B + W polarizing filter (may be that expensive of Lee and other providers are even better, but I can not imagine). The filter is beautiful narrow, the thread goes well, the effect is the way I imagine it. Absolute buy recommendation.
