Hello everyone,
I wanted to have a Rolleinar on my Automat I and on my Old Standard Rolleiflexes.
The Automat has a Bay I taking lens, and a 28.5mm viewing lens
The Old standard has two 28.5 lenses
Apparently, you can't put Rolleinars on 28.5 lenses, but instead, the Zeiss equivalent, called Proxar.
Focusing Distances Proxar
Proxar 1: 56cm à 1 m = 40 to 20 inches
Proxar 2: 25 to 50 cm = 20 to 10 inches
Focusing Distances Rolleinar
Rolleinar 1: 45cm - 1m
Rolleinar 2: 31cm-50cm
3: 24 -32
The problem is: they do not correspond exactly. The distances of Rolleinar 1 do not correspond exactly to Proxar 1.
How can we use these devices on an Automat, that has Rolleinar down, and Proxar up?
Another question: the RolleiPar or RolleiParKeil should be added on the top lens, to correct the parallax. Is is true also if a Rolleinar is used on the Rolleiflex 2.8F Bay III?
