The Cambo Wide 650 is a medium-format wide-angle technical camera designed for use with 6x12cm roll-film backs and a fixed wide-angle lens setup. It was built as a specialist tool for architectural and landscape work, offering a compact alternative to a full view camera when photographers needed a single fixed focal length on a rigid body.

At UK auction in today's market, hammer prices for the Cambo Wide 650 have ranged from around £600 to £940, with the two recorded saleroom results giving a midpoint near £770. Because only a small number of hammer sales are on record, what a Wide 650 is worth at any given sale depends heavily on the lens fitted, the condition of the helicoid and the presence of a matched roll-film back.
