Rodenstock APO Rodagon R 1:4 f=75mm 10602553 . $ 150
Special apochromatic lens for 1:1 dupes without visible quality loss. Used in professional slide copiers and in SLR cameras with bellows. Great results also when used as a macro lens. Has click stops (can be disengaged) and preset apertures. Symmetric lens configuration results in completely distortion-free operation and the apochromatic correction eliminates all color fringing
That's a giveaway price on the Dual Mode. Best slide duper out there, I have one and can attest to how good it is. Someone is going to get a good deal. Good combo with that lens also. Do you have the accessory slide stage holders for medium format, the box for 4x5 and stuff? Just curious.
