The Schneider G-Claron 305mm f/9 is a process lens with a 381mm image circle, covering 8x10in with generous movements. At 460g with a 67mm filter thread, it is exceptionally lightweight for a lens covering this format. The symmetrical six-element design excels at close distances but also performs well at infinity when stopped down. It is one of the most popular lenses among 8x10in landscape photographers due to its sharp performance and low weight.
