Thread: Filter Size Adaptor

    Default Filter Size Adaptor

    Hi Experts,
    Need to put on some filters like polarizing filter to CCTV lens
    with the filter size as "M40.5x0.5mm".
    Will appreciate any advice on how to mount standard sized filters
    to this lens and where to buy these adaptors.
    Thanks

    Richard

    B+W and Cokin make step up rings for lenses with 40.5 mm front thread. If I'm not mistaken, I believe Heliopan also makes step up ring in this size. I think that CP should be able to order one for you, because they sell B+W and Cokin products.

    Go to those old time photo stores. Peninsula got lots along the same row as CP. Or try K-13 Marketing on the 2nd floor.

    Don't be surprised they take out a shoebox with hundreds of rings.
