Q: 5. What's the difference between the Linear and Circular versions of 4 x 5.65 please? Do they both require a matte box with a rotating filter tray?

A: Here Linear and Circular refer to the type of Polarizing film in the filter. The confusing Circular term actually has nothing to do with the shape of the filter. It can be round or rectangular, it does not matter. A Linear Polarizer is be used in cameras without auto focus or auto exposure. A Circular Polarizer is to be use in today's digital cameras with their auto focus and auto exposure. You will need a filter holder/matte box with a rotating 4 x 5.56 to use this size Polarizer. However, we recommend that instead of a rectangular Polarizer filter, using a round one for it is much more practical, i.e., easier to use.

Q: 9. Can the filter take off from a mounted version to fit into Revar Cine Rota Tray? How the filter is fixed to the ring?

A: You can remove the mount but it's very difficult and you could damage the filter doing it. The threads on the mount are also very thin so you can damage those too. I would buy the unmounted one to use in the Rota pola tray. Nick

Q: 10. Can you confirm the threading on this filter?Is it 138mm diameter with 1mm pitch?How deep is the overall thread?What is the overall thickness of the filter? (or more importantly the thickness excluding the rear thread)Unfortunately the manufacturer lists very minimal information on their website and I can't find any detailed pictures to deduce the important dimensions from.

A: It is a 138 mm diameter but there are no threads on this filter. I use it in the rear dounut of a matte box.
