Hi, I love using filters for some of my work, and have recently heard about a filter system by wine country camera. While expensive(!), it looks innovative, and seems to address some of the issues with the existing holder systems. I use a Format Hitech 100mm system with various 100x150 and 100x100 filters (various brands) and a polarizer adapter/polarizer. While the wine country camera system seems to address some of the problems with existing filter holders, I am not sure about wood as a material choice, as well as price value (in the end the FH system does the job). It does have some intriguing features such as filter protection (scratching is an issue with the system I use, even if you are careful), the built in polarizer with less light leakage, and the claim of less weight/bulk. Does anybody have hands on experience with this system? I'd love to heard your thoughts! Here's a link to the company's website http://www.winecountry.camera Thanks!
