Karl,
Thanks for the suggestions - the lens is unmounted and looks as
though it has never been used. It will probably get used for 5x7 but
is an unknown quantity at the moment. I have been able to find out
very little about it - would really be interested in any feedback
from someone who has used a similar lens.
Thought you were rather keen on using that 360mm Tele-Xenar for
portraiture. Looking for something longer now?
There is a 15" Tele-Optar already in the kit bag for making
portraiture focusing difficult - nothing that a bit of rope and a
head board won't cure ;-)
Cheers,
Clive
