This excellent movie camera was introduced in 1951, in order to reach everyone. In fact, this camera is very simple and cheap. The model "II" was introduced in 1956 and was produced until 1958. It used a 8mm film, and was equipped with a lens Ektanon 13mm f/2.3 - f/16. The diaphragm could be regulated by rotating a ferrule, indicating the weather conditions (sun, cloudy, etc.). The viewfinder had three squares (green, red and orange). It was possible to add optic devices to the lens. The weight is kg. 0,750, and its size is 57x95x157 cm.
不知道这是不是8mm摄像机？
我从来没用过，也没有说明书。好像是和那卷8mm胶卷一起的，时间太久，忘记了。
