APO-Ronar Information Needed

greenspun.com : LUSENET : Large format photography : One Thread

Greetings, I am considering the purchase of a Rodenstock APO-Ronar 360 f/9: s/n 724559. Can anyone help me to determine the approximate age of this lens and if it is multicoated? Many thanx, DAB.

1935 assuming it is really a 6 digit serial number and that was several decades before multi-coating technology was developed.

If the serial number is a 7 digit number starting with a 7 it is an early 1970 version

You may be able to determine if it's multicoated just by looking at it. Take a look at Terry Thalmann's page on Fujinon lenses (http://largeformat.homepage.com/fujinon.htm) as a reference. He shows some very instructive photos of how single coated vs. multicoated lenses reflect light when viewing the lens surfaces under a lamp.
