Gradually I found that I need a gray filter for some pictures. Looking for a filter I found inter alia the above, since the reviews were fine and also bought the price ....
After more than 3 weeks in use and many different shooting situations, I can say the filter is to be good value for money, and I have found that it is a quiet 10 Graufilter could have been because I sometimes come across with the 6 to the limits.
