This thread is for information on a lens I recently acquired: it is a LTM Elmar 90.
The aperture ring ranges are from 4 (of course) to 32 it is chrome with letherette on the base near the mount (less than 1 cm wide more or less).
Detachable head for visoflex use.
Lens number is 1382xxx which dates back to 1955.
The strange thing is that it has two filter rings: one it seems 34mm and the other 39mm and I never saw this strange "double filter" configuration.
I tried to unscrew what could be a step-up ring but unsuccessfully: maybe is too tight or maybe...it is not a step-up ring at all!
Do you have some information or ideas that can help me improve my knowledge on this beautiful lens?
Thanks in advance,
ciao
