If one still has no filters and even want to try around (beginners) This is the set that you should buy. Already the Krativitätsschub is it triggers justified for the price. Disappointed me the CPL, which results in little loss of quality, and also performs not quite as expected. Total amazed me the adjustable ND because I least expected, but that's better than me. The rest is OK. I'm going to look especially I enjoy what filters and then exactly the which I often need and not have the power that I want to replace with higher quality products. The set is better than expected and all filters (also CPL) are useful.
I have no comparison with expensive products and am not a professional, this review is therefore again what someone like me can expect when making a purchase. I hope that helps.
