I had a filter that costs only about 1/3 of a brand filter, not too much versprochen.Aber in this case is cheap and good, indeed very good. Clean processing, the thread can be easily yet tighten and loosen as well again. So I continued to look for the 'Haken.` RAW -Probeaufnahmen with the EOS 7 D and L-lens, sometimes with, sometimes without gray filter, verglichen.Das result, the computer at 100% stunned, I could see with the naked eye, no differences except for the mentioned already in other recessions blue cast. This can, however, in a RAW converter easily correct. Color reproduction and sharpness were both shooting indiscriminately. Perhaps this requires a measuring device. Making a difference to one of my other, far more expensive filter there yet: the packaging is a little less well. Who can do without it, must not have doubts when buying this, coming from Chinese production accessories.
