Schneider Super-Angulon 90mm f/5.6

Schneider Super-Angulon 90mm f/5.6 is the classical 4×5 wide-angle Schneider LF lens — equivalent to roughly 28mm on 35mm. Among the most-recommended LF starter wide-angles, balancing wide perspective with usable movements, modest size, and abundant used-market availability.

Key features

• Focal length: 90mm
• Maximum aperture: f/5.6
• Image circle: ~235mm at f/22 — covers 4×5 with generous movements; covers 5×7
• Optical formula: 8-element/4-group symmetrical wide-angle
• Multi-coating on later production (older single-coated copies common)

Use case + rendering

The 90/5.6 Super-Angulon is the universal 4×5 wide — bought by virtually every serious 4×5 landscape and architectural photographer at some point. The 235mm image circle gives substantial front rise for architecture and full corner-to-corner illumination on 4×5 with shift movements applied. Sharp by f/16, very sharp by f/22.

The f/5.6 maximum aperture is bright enough for ground-glass focusing in moderate light — a meaningful advantage over the f/8 Super-Angulons for field work.
