Instructions. Case.Designed by Kaufmann. In Britain, the Posographe was sold by Sinclair for a number of years.
The design of the Posographe is quite ingenious, it is based on a number of levers hidden inside the meter, these are inter-connected and connected to six pointers around the edge of the meter. The pointers are adjusted to indicate the conditions, time of day, subject etc., a further pointer will then indicate the exposure.
