You may want to look into Xume magnetic rings for fast and easy changing of filters and lens cap.

Ok...I've come to the conclusion that these ND filters are simply junk. Thankfully, I didn't pay all that much for them. All of them produce a milky effect no matter where I aim in relation to the sun, close the gap between the filter and filter holder with black tape, or anything else. So, in the near future, I'm going to buy a quality screw in filter set of ND 2, 4, 8, 16, and the big stopper. Thanks for all the tips. Ken
