Introduced in 1974 the 4000 is the evolved version of the model 2000 with a more luminous objective with a 26mm lens and a variable exposition controlled by an electronic shutter. The camera also has variable shutter speeds of 1/250 of a second to 30 seconds and the focus selected with pictograms of a Mountain, a two person Group plus a person from the waste up. These pictograms are accompanied by a scale of distance (in blue characters), in feet or meters coupled to diagrams for the utilization of the Magi cube at distances of 4m, 2m, and 1 to 2m. An LED in the finder indicates the correct exposure and if you have to use the flash. When you insert a Magi cube this automatically fixes the shutter speed on 1/50 of a second. The identifiers on this camera are "AGFAMATIC 4000", "pocket", and the Agfa logo engraved in black. On the front panel, "AGFAMATIC 4000" and "sensor" in white print located on the top panel.
Also a bright red shutter button, hidden viewfinder until opened, and a ¼ 20 tripod socket with a handy carry strap screwed in it.
