zeiss super ikonta 531/2 mx filters, update.

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

Hallo Larry,

this Zeiss filters fit on the Contax rangefinder lenses in 40,5 mm screw mount and 42mm slip on filters.
