Karl,
The Rodenstock lens that I am using is a APO D lens.

APO-Rodagon-D
Not necessarily enlarging lenses, these models are optimized for near
1:1 reproduction ratios, for purposes such as duplication of
transparencies, or preparation of internegatives. They are 6-element,
4-group designs, and optimum f-stop is 2 stops below maximum aperture.
* APO-Rodagon-D 1x 75 mm f/4 (for 6×6 cm)
* APO-Rodagon-D 2x 75 mm f/4.5 (for 6×7 cm, optimized for 1.2x-2.5x
reproduction)
* 120 mm f/5.6 (for 4×5 in)
APO-Rodagon-R
Optimized for 1:1 reproduction ratio.
* APO-Rodagon-R 75 mm f/4
Does anyone know what type of lens is/was used in the Imacon scanner?
