[Leica] It's a film camera! Rangefinder at that!

[hoppyman at bigpond.net.au (G Hopkinson)]

Thank you to everyone that posted information on this for me. All knowledge 
is golden. Looking at the pictures of Fujifilm GS645, I
guess that the new design might share its operation.

Thanks again all
Cheers
Geoff

Hoppy wonders how old RF folders coupled. Well,...      

The Zeiss Ikon Super Ikontas did not have a physical coupling. Rather, one 
of the RF 'eyes' in the body looked through a pair of
counter-rotating optical wedges on the front lens/shutter standard. 
Rotating these wedges (thumb-wheel) also rotated the (focusing) front cell 
of the lens, as well as converging the RF eyes in the
body. The wedges were on an arm that had to be folded down before closing 
the camera.

OTOH, the Voigtlander RF Bessa 6x9 focused with a knob on the body. This 
racked the entire lens/shutter standard in/out, as well as
converging the eyes.

Then there's the Kodak Retina 35mm RF. Focusing was by a helix moving the 
lens/shutter in/out, with a follower arm back to the rf
optics in the body.

Whether any of these methods applies to the Fuji, I dunno, though its 
lens/shutter standard or yolk looks like the Bessa's.

This is pretty far OT. Sorry about that. Except.... Leitz did make an Elmar 
for (AFAIremember) the Kodak Vollenda folder, didn't
they? So, thinly on-topic. Very.
