It is recommended to stop down to at least than f/22 for use at infinity. They are available in barrel mount, as well as mounted in shutters. Coverage listed at 1:1 150mm f/9 (for 8x10") 210mm f/9 (for 11x14") 240mm f/9 (for 14x17") 270mm f/9 (for 16x20") 305mm f/9 355mm f/9 (for 20x24") G-Claron WA A wide-angle process lens with 4 elements in 4 groups, optimized for reproduction ratios between 2:1 and 1:2. The 270 mm lens has an angle of coverage of 72°, the 240 mm has 80°, and the 210 mm has 86°, which give these lenses gigantic image circles, though the image softens considerably near the edges of coverage. 210mm f/11 (for 20×24 in) 240mm f/11 (for 16×20 in) 270mm f/11 (for 20×24 in) Repro-Claron The Repro-Claron is a line of 4-element, 4-group lenses optimized for 1:1 reproduction ratios, but still usable at infinity. The f/9 lenses also have a slot for between-the-lens filtration or Waterhouse stops, the latter of which are available in f/128, f/180, and f/260. 55mm f/8 135mm f/8 210mm f/9 305mm f/9 355mm f/9 420mm f/9 485mm f/9 610mm f/9 Apo-Artar Apo-Artar lenses are an apochromatic symmetrical 4-element design, which is optimized for 1:1 reproduction. These lenses give 46° of coverage up to 480mm, 40° in 890-1065mm, and 38° in 1205mm. Coverage listed at 1:1. 240mm f/9 (for 4×5") 360mm f/9 (for 11×14") 480mm f/11 (for 11x14") 610mm f/11 (for 20x24") 890mm f/14 (for 30x40") 1065mm f/14 (for 33x46") 1205mm f/14 (for 40x50") Apo-Artar HM Apo-Artar HM lenses are an apochromatic symmetrical 6-element design, which is optimized for 1:1 reproduction. The HM in the name indicates that these lenses use high-modulation glass elements. 75mm f/4 (up to 6x7 cm) Macro-Symmar HM The Macro-Symmar HM is a variation of the Symmar design, engineered for 1:1 macro work
