195mm f/6.8 (for 8x10") 210mm f/5.6 & 370mm f/12 (for 5×7") 210mm f/6.8 (for 10x12") 240mm f/5.6 & 420mm f/12 (for 8×10") 240mm f/6.8 (for 11x14") 270mm f/6.8 (for 14x16") 300mm f/5.6 & 500mm f/12 (for 8×10") 300mm f/6.8 (for 16x18") 360mm f/5.6 & 620mm f/12 (for 11×14") 360mm f/6.8 (for 16x20") Symmar-S The Symmar-S is an incremental improvement to the original Symmar design, adding multicoating to the feature set. The lens is not symmetric like its predecessor and is not convertible. The available focal lengths are slightly different, with the subtraction of the 80 mm, and addition of a 120 mm and two 480 mm lenses of varying speeds. 100 mm f/5.6 (for 6×9 cm) 120 mm f/5.6 (for 4×5 in) 135 mm f/5.6 150 mm f/5.6 180 mm f/5.6 (for 5×7 in) 210 mm f/5.6 240 mm f/5.6 (for 8×10 in) 300 mm f/5.6 360 mm f/6.8 (for 11×14 in) 480 mm f/8.4 480 mm f/9.4 Apo-Symmar This is a 6-element, 4-group apochromatic lens design, which has since been replaced by the Apo-Symmar L-Series. Using low-dispersion glass and multicoating techniques, secondary-spectrum reflections have been greatly reduced. The Apo-Symmar lenses up to 360 mm have a 72° angle of coverage, and the 480 mm lenses give a 56° angle. 100 mm f/5.6 (for 6×9 cm) 120 mm f/5.6 (for 4×5 in) 135 mm f/5.6 150 mm f/5.6 180 mm f/5.6 (for 5×7 in) 210 mm f/5.6 240 mm f/5.6 (for 8×10 in) 300 mm f/5.6 360 mm f/6.8 (for 11×14 in) 480 mm f/8.4 480 mm f/9.4 Apo-Symmar L-Series This is a redesign of the Apo-Symmar line, using new environmentally friendly glass compositions and incorporating slightly more coverage. These are 6-element, 4-group apochromatic lenses with a 75° angle of coverage. 120 mm f/5.6 (for 4×5 in) 150 mm f/5.6 (for 5×7 in) 180 mm f/5.6 210 mm f/5.6 (for 8×10 in) 300 mm f/5.6 480 mm f/8.4 (for 11×14 in) Super-Symmar HM These are 8-element, 6-group variations of the Symmar line, which feature an 80° angle of coverage. The HM in the name indicates that these lenses use high-modulation glass elements. 120 mm f/5.6 (for 4×5 in) 150 mm f/5.6 (for 5×7 in and 4x10 in) 210 mm f/5.6 (for 8×10 in) Super-Symmar XL These are wide-angle lenses of a 6-element, 5-group aspheric design, which give a 105° angle of coverage. These lenses are also heavily corrected for chromatic
