    Odd-sized filter

    Now that it's finally nice, it's time to get out and use the Speed Graphic. I'd love to get a circular polarizer for it, but the lens itself doesn't have any threads for filters. It's got some sort of doohicky clamped to the outside of the lens ring that can be unscrewed and I've got some assorted filters that slip behind it. I can't seem to figure out what size the threads are. The local camera guy thought it might be a No. 6 or 7?? I've never heard that. A caliper says that it's approximately 44mm...

    Any ideas?

    It sounds like a 'Series' filter: http://en.wikipedia.org/wiki/Photogr...Series_filters

    Here's a Series VI circular polarizing filter.

    You would probably be better off getting a universal square filter system.

    Best,

    I was really hoping to get a step ring and then use conventional round filters. I just don't see a step ring from Freestyle that would seem to work...any ideas?

    Take it to a local machine shop and have them identify the thread diameter and pitch and that could give you a start.
    Thank you. ChrisW

    My graphic has a series of lens hoods the screw into one another and allow filters to be inserted between the hoods. This was made by Kodak to press fit over the primary lens. It should be available on e-bay.
