Well it's actually about 6.8 - Pentax bellows M with 50 mm f 1.4
reverse mounted at full extension and a 2 time teleconverter between
camera and bellows.

The Mecablitz tube is just in parallel with the AF240 and all the
controlling is done by the AF240. When I was putting it together I was
slightly worried about the extra drain being too much for the
components in the AF240 but it's been used for over 100 pictures so far
and test fired several hundred times on a Z1p and SF1n.

No pics as yet, but I intend to at some point. The setup is not really
pretty but it does work well - I built it as a prototype but unless it
physically falls apart I probably won't change it. All exposure
control is done TTL, I haven't got hold of a flash meter to test manual
modes.
