The Fujifilm Fujinon A 180mm f/9 is a compact apochromatic large format lens with a 252mm image circle. At just 170g with a 46mm filter thread, it is one of the lightest large format lenses at any focal length. The A designation indicates a four-element apochromatic design optimised for sharpness and colour correction. Despite its tiny size and weight, it covers 4x5in with generous movements and even covers 5x7in, making it a favourite among backpacking photographers.
