The Linhof Kardan Bi-System is a large format view camera produced by the German manufacturer Linhof. It is a studio and field camera offering the movements expected of a monorail-style technical camera.

Auction data for the Kardan Bi-System is thin: the only recorded UK hammer result is £400 in June 2024, which sets the current reference point for what one sells for at saleroom level today. Because this is a wholesale auction figure rather than a dealer asking price, retail values in 2026 will typically sit above this, and condition of the bellows, standards and rail will materially affect what an example is worth.
