The Super-Angulons are Biogon designs, making for huge, heavy lenses, but also giving very generous angles of coverage. The f/4 lenses give 95° of coverage, the f/8 models give 100°, and the f/5.6 units give a 105° coverage angle. The f/4 and f/5.6 lenses are 8-element, 4-group designs, while the f/8 lenses are older 6-element, 4-group, symmetrical designs. Coating technologies improved along the production life of these lenses, and recent Super-Angulons are multicoated. 47mm f/5.6 (for 6×9 cm) 47mm f/8 53mm f/4 (for 6×7 cm) 65mm f/5.6 (for 4×5 in) 65mm f/8 75mm f/5.6 75mm f/8 90mm f/5.6 90mm f/8 120mm f/8 (for 5×7 in) 121mm f/8 165mm f/8 (for 8×10 in) 210mm f/8 (for 11×14 in) Super-Angulon XL This is an update of the Super-Angulon lens design, incorporating modern glass and multicoating technologies, and an expanded angle of coverage. 38mm f/5.6 (120°, for 6×9 cm) 47mm f/5.6 (120°, for 4×5 in) 58mm f/5.6 (110°) 72mm f/5.6 (115°, for 5×7 in) 90mm f/5.6 (110°) Symmar The Symmar is one of the original Schneider designs, introduced in 1920, and is still relevant and used today. They have a 6-element, 4-group, symmetric design, and give a 70° angle of coverage. The f/5.6 series of lenses are "convertible", meaning that by removing one of the lens cells the user creates a 3 element lens of longer focal length than the complete lens. The resulting 3 element lens has a narrower aperture of f/12 and an angle of view of 40°. These lenses have two aperture markings, one in white for the complete lens and one in green for the converted lens. When "converted" the resulting 3 element lens will produce softer images than the complete lens.
