On older models the flange may be replaced at any qualified service shop to accommodate the attachment. Other adjustments can be made as required, according to accompanying instructions.

The device is called the Kin-Dar hypostereo attachment,* "hypo" because the lenses are set at less than normal interocular separation.

Photographs down to 3 in. from the subject are possible, with a surprising amount of depth even with small aperture shots, although it is best to have backgrounds and foregrounds fairly close to the main subject. The attachment has been planned for precision at fixed distances, so
