Schneider Betavaron 50-125/4.1 [V1]

Zoom enlarger lens marked “3…10/0.08”, referring to the 3x-10x magnification range selectable without varying the negative distance. An optional two-element supplemental lens (VL) increases the range to 5.3x-17x. Later versions have revised branding and apparently improved multicoating.
