Roughly estimated 2-15 cm., depending on magnification. If there is
enough space for a mounted flash (ring or T28)? That would depend on
the solution how you attach them. For instance, when the Bellows is
horizontal, I can let my ringflash rest on the 38mm macro, and this
works; only to operate the aperture set ring(s) (I have the manual
macros) I would have to (re)move the flash. If you would mount a
ringflash as they're supposed to (like a filter, using some adapter),
the highest magnifications would no longer be possible. The solution
that would work best, I guess, would be some way to mount either the
T28 twins (which I don't have - yet) or two T32's on the Bellows front
plate. But how do you attach two hot shoes firmly to this plate in such
a way that they can easily be removed?
