Ikon VS Nikon S (mounts)

Thanks for the link, very interesting. Hard to see why you would do it that way, but it seems Nikon did. More samples would help get a better picture, though. n=1 for each camera isnt really proving a point.

And my little niggle - Contax would be better to use in the post name rather than Ikon. Zeiss Ikon was the company name (Zeiss Imaging if you like) while Contax is the family name for the RF cameras.

his website is perhaps not as accurate as his reputation suggests


the German standard for thread pitch is based on a microscope , which is 26 threads per inch (English standard)
Japanese manufacturers assumed leitz and Zeiss mounts were metric (25.4 threads per inch )this appears to be the mount difference .
the leitz standard focal length differs from Zeiss , Nikon was using the leitz standard focal length, so this adds to the difference .


please correct if I am wrong

I think just confusing two issues. Contax and Nikon lenses are regarded as being able to mount to either camera but previously said to have different focus thread pitch. This testing suggests identical thread but different, fixed distance between mount and film.

Correct. That was common knowledge already in ancient China, ancient Egypt, ancient Greece — apparently not so much in certain «great again» areas of our planet!
 
Thanks! not sure who the guy is but I sense some negativity towards him. :eek::eek::eek:

would it be better if we just delete this instead since his info is wrong? Sorry about that
