Too bad you couldn't get a faster synchronized shutter unit, for fast
flash sync. 105mm is a little long for a portrait lens on APS-C but
you'd be the envy of all those medium format users who want leaf
shutters fpr high sync speeds.

The lens is a 105mm f/4.5 Carl Zeiss Jena Tessar (mounted in a Compur
0s shutter) that was borrowed from a circa 1930 Maximar 207/3 (which
is a mini 6x9 view camera). It's mounted to a drilled out m42 body
cap. That was screwed into an Asahi Pentax Bellows II, to which my
K-3II was mounted with a screwmount to K adapter. The Compur shutter
is set to T (left open) and the DSLR controls the exposure.
Believe it or not, this combo achieves infinity focus, something I
could NOT get with my earlier attempt at this idea:

I used a plastic body cap for this proof-of-concept, but I think I
will see if I can find a metal m42 body cap to do it For Realsies.
