Schneider Componon 28/4 [V5]

Six-element enlarger lens with black plastic barrel and green aperture window. Most (earlier) models  [V5] have a 15mm front element, flush rear cell assembly with a broad retaining ring and Convex-5 aperture. However in 1991 there was an undocumented [V6] which has a 16mm front element, a protruding rear assembly (H2=5mm) using narrow retaining rings, and the Makro Iris diaphragm. Image circle insufficient to cover full frame at infinity, but prized for macro performance when reversed. [US Cat# 10-037275 (?)]. Product images by CloseUp Photography >
