I am in the market for a set of graduated neutral density filters and would like to know what your thoughts are regarding manufacturers. When it comes to filters, normally I go with B+W or Heliopans, but neither of these manufactures seem to make the 4x5 or 4x6. I want the rectangle because I would like to be able to adjust the line as needed. Any suggestions on manufacturers of high quality rectangle filters is appreciated.





Thanks


Bob
