The Schneider 150mm Componon-S is one of the top professional enlarging lenses. It is a 6-element, 4-group lens that is corrected for flat field, high contrast transfer, and excellent definition over the whole field. The 150mm lens provides coverage for 4 x 5" negatives.

The high performance of the Componon-S is maintained even at high magnifications. This Componon-S lens has a M50 rear mount thread, and is fitted in to a barrel with a click stop aperture scale.
