This remains to be confirmed, but the few tests performed this summer, I was quite pleasantly surprised with the result. Then of course, the white balance is correct (are shooting RAW), but I have not found the cross effect and I managed to get some nice shots with this filter. I took it for fun, if I wanted a pro stuff, I'm facing a B + W 110 or other filter to + 100 Euros, which would have given me a much better quality. Only regret: Very difficult to see the density that is used, so I am forced to take my photos via the screen of my 700D to be able to MAP on the manual with the mounted filter. Finally, if you want to try the long exposures, you do not take big risks to buy this filter.
