[LargeFormat] TWO versions of Rodagon 300mm?

[Lee Carmichael]

I have never heard of two diffrent versions for the graphic arts lenses.  I
could be mistaken.  Vertical cameras were designed to be used in the
darkroom and save space.  Horizonal cameras take up a lot of floor space.

I guess I'm not fully understanding what you mean in your post below.

I thought that "Rodagon" was Rodenstock's designation for an
enlarger-type lens where the reproduction ratio was optimized to be
between 2:1 and 10:1. However, what concerns me is that horizontal
cameras are almost ALWAYS used to copy 1:1. So is it possible that
Rodenstock made TWO DIFFERENT VERSIONS of the Rodagon -- one optimized
for 1:1 (i.e. horizontal applications) and another optimized for 2:1 to
10:1 (i.e. vertical applications). Their literature makes no mention of
any such distinction -- is it possible that in the past there was a
difference?
