This circular polarizing filter from Walimex is not the first that I use on my lenses, and I can already notice in advance that I am, as always, very happy with it. The filter is very well made, the fine threads are fit, the multi-coated glass has, in my view a good quality, and also the bezel is pleasantly smooth, so that the desired position can be adjusted easily. The Walimex Pro comes in a carton including Hard, which can also be used for secure storage. My short conclusion: This Polarizer from Walimex I think is in any case highly recommended, in particular, not least at this excellent price / performance ratio.
