Apparently there are a wide variety of zone vi cameras made. I read that the first were made similar to the wistas. I have seen tachiharas that were marketed as zone vi. And a local camera store in Sacramento is selling a zone vi with a brass plate marked 'made for zone vi by ron wisner'
(camera arts on 57th and h st.)
So is there a web site that shows the differences between the various zone vi models? I have read conflicting reviews of the zone vi, and perhaps the different versions have created much confusion.
