Looking around Ebay I saw a Voightlander Bergheil 9x12 with a 120mm Heliar lens. It looked like the factory lens as the depth of field chart was marked 120. I was wondering if the 9x12 Bergheil came from the factory with a variety of lens choices? I would think that 135mm would be the standard choice. Also it would seems like 120mm would have tight coverage on 9x12cm limiting the use of the camera rise/fall and shift. I assume the Heliars cover 60-65 deg. Does that sound correct for the ones that came on these Bergheil cameras.
