This model is distinguished by the convenience of a Graflok back assembly offering increased compatability with roll-film backs (especially 6x12 format backs) and Wista's own binocular reflex housing. Constructed entirely of seasoned cherrywood to ensure strength and beauty, the Wista Field-45 DX models eliminate the possibility of warping. The hardware is brass, the corners skillfully joined with durable tongue and groove joints. The hardwood and brass give the DX beauty and durability. DX models will accommodate short focal lenses up to 65mm without the aid of a recessed lens board. Most lenses from 120 to 150mm in length, can be left on the camera when transported (mounted backwards), saving set-up time and space in your camera case.
