The Ensign Autospeed is a folding camera for 2¼x3¼-inch pictures on 120 rollfilm, unusual in having a focal plane shutter. It was made from the early 1930s by Houghton-Butcher. It is metal-bodied, with leather covering. It is not self-erecting. It was offered with a 4-inch f/4.5 Aldis Uno Anastigmat, an f/3.4 Aldis-Butcher, an f/3.5 Dallmeyer Dalmac, f/4.5 Ross Xpres or 105mm f/4.5 Tessar. The lens standard has rise and cross lens movements, and focusing is by a radial lever on the right of the bed, with a scale on the left, down to 4 feet. There is also a brilliant finder, and a wire-frame finder. One model of the camera was made with a coupled rangefinder mounted on the left side of the body.
The shutter has speeds from 1/15 - 1/500 second, plus 'T'. There is a shutter release button on the body, and the camera was supplied with a short cable release, which attaches directly to the shutter.
Ensign's catalogue boasts of 'automatic' film-winding; this refers to a combined knob which both winds the film (aparently not requiring the red window except when loading a new film) and the focal-plane shutter. The same knob incorporates the shutter-speed control.
As in several of Ensign's cameras of the time, there is a 'film registration device'; a mechanism which increases the force of the pressure plate. In this camera, this is activated as the shutter release is pressed (whereas in many cameras, this mechanism is relaxed by opening the red-window cover).
