Manuals and Technical Documents for ALPA Schneider Lenses

Since the beginning of the ALPA Medium Format era, lenses from Schneider Kreuznach were part of the ALPA photographic plattform. Being mostly true symmetrical constructions, these lenses featured rather large image circles and a stable performance from infinity down to a scale of 1:4. Center Filters cured the often very prominent vignetting / edge light fall-off. ALPA used / uses the brands Helvetar and Switar for dedicated lenses. The Helvetar 5.6/48 mm is still one of the most flexible lenses for analog and digital use and the lens with the highest production numbers. It was retired with the arrival of the extraordinary Helvetar 5.6/43 mm lens.

The following ALPA lenses from Schneider Kreuznach bear the name Helvetar / Switar:

Helvetar 5.6/28 mm
Switar 5.6/36 mm
Helvetar 5.6/43 mm
Helvetar 5.6/48 mm
