Focus drive

[Phil Brammer]

Does anyone have any methods of focussing mechanisims for a 6x17 camera (homemad e)? I previously had a 90mm angulon f6.8 in a PVC screw off endcap and associate d threaded section from a plumbing supply; that worked O.K., but now the SA90 f8 i have is too big! soemthing like a rack and bellows, or something like the Fuj i or Linhof 617's focusser, how is the focussing mechanisim arranged on these ca meras?

Thanks in advance

Phil

Rodestock makes a focus mount for the 90mm 6.8 Grandagon which can be ordered from any camera store. They also make focusing mounts for all of their wa lenses from 35mm up that are in a 0 shutter.

There is also a Rodenstock focus mount for enlarging and duplicating lenses in Leica mount or C mount.
