This Linhof viewfinder was designed for the Linhof Technar camera, but it can be used for any 6×9 camera with a 65mm lens (there are a few!) The mounting shoe is the slightly nonstandard Linhof configuration, but it will fit in many ISO shoes with a bit of extra overhang. In excellent condition, with light wear. These viewfinders have interchangeable masks for different formats, but only the 6x9cm mask is included.
