  1. Hi,
    Recently i purchased a few Zeiss Ikon filters on E-Bay (from a very
    nice gentleman)on the off chance that they would fit. Previous posts
    have suggested that the filters required would be 40.5mm push fit?
    The items purchased have a strange "knurled" thread & screw perfectly
    on & off (backwards) to the camera (male
    thread .....also "knurled" ??)lens ring.
    The filters are in bakelite hinged boxes & have 373/4 germany, Zeiss
    Ikon marked on the rims. Has anyone come across this also ? My
    reasoning is, if in fact the lens will accept a female 40.5mm thread,
    i could also mount a 40.5 mm polarizing filter on backwards !!??
    Which is my aim.
    Cheers, Larry
