Schneider's premium Componon-S — the 150mm for finest 4x5 large format enlarging.
The Componon-S 150mm f/5.6 is Schneider's top-tier large format enlarging lens, delivering maximum performance for critical 4×5in large format printing in professional fine-art and commercial darkroom environments. The premium multi-coating reduces flare and maintains colour accuracy across the large image circle required for 4×5in coverage.
150mm focal length, f/5.6 maximum aperture, Schneider Componon-S premium multi-coated, M39 thread mount.
Among the best-regarded large format enlarging lenses, the Componon-S 150mm competes directly with the Nikon Apo-EL Nikkor and Rodenstock Apo-Rodagon for fine-art large format darkroom work. Exceptional performance at f/8–f/11. Carries a significant price premium over the standard Componon.
Inspect elements for haze and coating condition; the premium optics justify a close inspection before purchase. Check M39 thread and lensboard compatibility. Aperture blades should be pristine. Verify the S designation markings.
