Dear all,
I have just been given these two lenses, a coated 24cm f:4,5 Heliar and a 13.5cm f:4,5 Doppel Anastigmat Eurynar. Being totally unexperienced with vintage lenses, here are my questions:
1. Regarding the Eurynar, the serial number gives it a 1925-28 vintage, so it should be uncoated. However, the reflections of the front element go from green to purple, and on the rear element from purple to straw yellow. Could it have been multicoated later? On another note, what is approximate coverage of the lens - will it cover 4x5? Maybe Ole can help me on this.
2. The Heliar is beautiful, but… it has what seems to be cement/balsam failure. Please see the pictures attached. What is it and is it worth cleaning/repairing?
Thanks!
