Hi, I'm using 55mm thread Minolta Rokkor lenses in front of my video camera - they are a 50mm 1.2, a 50mm 1.7 Macro and a 24mm 2.8. I am shooting a project outside on a sunny day and would like to use a polarising filter. In the digital imaging age, there is plenty of information about circular polarising filters but not much on linear polarising filters. I need several well-built linear polarising filters that will not cause too much vignetting - especially a concern on the 24mm lens. The image will hopefully make it to cinema screens so minimising distortion is also a concern. Any advice appreciated!
