FYI: I have purchased the filter here for 89.87 euros, because I'm just afraid that the current price is about 160 euros.
Among the findings: I am far happier than the Billigset. Price performance is definitely in order. I can not notice any discoloration and change system with the appropriate modular holder (100mm) of Hitech aluminum is really good. I step itself a very ambitious photographer who has rather higher demands on his photos, but I could not imagine what could make a better LEE Filters.
The package consists of the 3 pictured filters (0.3, 0.6, 0.9) and nothing else. A bag you may have to even buy one at that. I opted for a "Lowepro SF Filter Pouch 100". The filters fit in there all good pure and it also seems to be very stable.
I can not compare the filters Cokin filters or Lee filters, a buy recommendation I can say yet :)
