The Aerotronica 69 is an aerial camera made by Linhof in 1983.[1] It makes 6x9-cm images on 70 mm film in a motorised magazine, allowing 320 exposures in one load.[1][2] Lenses from 75 to 480 mm in focal length can be mounted by means of an adjustable lens-tube.[3]
The camera relies on an innovative focal-plane shutter, composed of two discs, each with a slit, rotating continuously at slightly different speeds. A third shutter covers the rotating discs, and is opened to allow an exposure. [4] The speed of the rotation of both discs is adjustable, giving a range of six speeds between 1/500 and 1/1500 second.
The camera has a frame-finder, with red and green LED indicator lamps in the eyepiece loop; these presumably indicate the state of readiness of the camera.
The camera can be powered by mains electricity or a battery pack.[3] A data-back was made for the camera.[3]
