Zone VI field history??

In the KEH catalog, they list three Zone VI field cameras

distinguished by the following in parentheses :

Wisner

Zone VI

Wista

Does anyone know the history here. I assume the Zone VI is the

current model and I am aware that Wisner was involved in the

one of the original Zone VI cameras. Where does the Wista fit

in??

<p>

Cheers, Richard

If you can find an old copy, or maybe even a new copy of Picker's

Zone VI Workshop, in the rear catalog pages you'll the camera in

question illustrated. It is a Wista with the Zone VI name plaque

affixed. Which Wista model I forget, but it's the one without rear

shift. What alterations to the design or construction Fred requested

or made, I'm not sure either.

Ron Wisner designed and briefly built the 2nd incarnation of the Zone

VI, and then went into bidness on his own. The most recent Zone VI

is essentially the same as Ron's original, but not his own current

production.

Ah, here it is.

According to Fred it weighs 3.25 lbs, has 12" of draw, is made of

cherry, has rise, fall, swing & tilt on the front, and rear base tilt

& swing.
