The Schneider Tele-Arton 250mm f/5.6 is a telephoto-design large format lens with a compact 158mm image circle, covering 4x5in with minimal movements. At 810g with a 67mm filter thread, the telephoto design provides a significantly shorter back focus than a conventional 250mm lens, allowing use on cameras with limited bellows extension. It is designed for field photographers who need longer focal lengths without carrying excessive equipment.
