The Ihagee Zweiverschluss Duplex is an early German plate camera produced by Ihagee of Dresden in the early twentieth century. The name translates as "two-shutter Duplex", referring to its use of both a focal-plane shutter and a sector shutter in the same body, allowing the photographer to choose the appropriate mechanism for the lens and subject.

At UK auction, hammer prices for the Ihagee Zweiverschluss Duplex have ranged from around £130 to £500, with the limited record set giving a midpoint near £310. Today the value of any individual example is highly condition-sensitive, and saleroom results vary widely depending on shutter function, bellows integrity and the lens fitted, so any quoted price should be treated as indicative rather than a firm market level.
