OK here's the deal. I own a Sony F828, and after purshcasing a polarizer filter with a 1 2/3 stop, I noticed I could get a shallower DoF in sun situations due to being able to shoot wiht a larger aperture. I also know that I can use the filter like a ND filter so as to use longer shutter speeds with my not small enough F 8.0 max aperture.
Anyway, I've decided I need some ND filters. With the research I've done, I've had mixed results with brands, but I think B + W is out of my wallet. I've heard good things about Heliopan, but that might be too expensive also. What brand do you recommend as good but not so expensive? The polarizer I got was a Kenco for 50.00, but I haven't heard much good about them. Should I replace it and stay away from Kenco?
My camera has a max A of F 8.0 and S of 30 seconds.
