Hello, I wanted to check and see if anyone had tested, used, seen footage, reviews, or anything on Skier IRND 4x5.6 filters. I have searched the net and I'm not having any luck. I have a set (.3 - 1.2) plus a pola at a camera house and it's coming in at 1500.00 I can get a set of Skier's for 600.00. Now I know you get what you pay for but it's worth checking because you never know. Any help would be appreciated. Thanks.
