I recently purchased a Kern Switar 10mm f1.4 lens, which appears to be in good condition, for use on my Bolex EBM with a c mount adapter.
However, when mounting this lens I encountered a strange problem where it would only focus at extremely close distances and leaves the rest out of focus.
Seems like this lens is not in such great shape after all but wondering if anyone knows a fix?
Thanks for any help!
