[UV] RODAGON lenses for UV

As I was testing (again) lenses for UV photography, so I ran a few more spectrometric tests now on Rodenstock (now LINOS) RODAGON lenses, which might be of interest. These are thread mount enlarger lenses:

Rodagon (old "zebra" type) 5.6/150mm, 5.6/135mm, 4/80mm (newer type) and the modern 4/75mm Apo Rodagon D

UV transmission graph:

In terms of UV transmission, quite unexpected good UV transmission, surprisingly also the Apo Rodagon D type. Not having done focus shift tests, but would assume it's there.

Stay tuned, more will follow on that fascinating subject...

More info on this very interesting field may be found on my site
