Is there any info on the filter size of the 4,5/135mm Skopar lens of Voigtlander Avus (9x12) camera? I made some research on the net and according to the original manuals, it has 36.8 mm filter size - I am not sure whether I would need screw-in or push-on filter.
Basically, I would like to use (36?)37--->49 mm (screw-in) adapter - is it possible?
Please help - any info would be highly appreciated.
