First produced in 1962, the Agfa Optima 1a or Agfamatic was one of the first fully automatic scale-focusing 35mm film cameras. The successor to German camera manufacturer Agfa's Optima 1 camera, the camera employed a selenium cell that generated a voltage related to the luminance , to both measure the light level and to provide the power ...
The Agfa Optima 1535 Sensor is a 35 mm rangefinder camera manufactured by the German company Agfa in 1977. It has the typical big finder of the Optima series, but on this special model it is combined with a superimposed coupled rangefinder. Shutter speed is controlled electronically by a CdS meter, with speeds from 15 sec. to 1/1000 sec. A ...
Agfa Optima Flash Sensor. The Agfa Optima Flash is a fixed-lens 35 mm viewfinder camera manufactured in Germany by Agfa from 1981 to 1983. It belongs to the Agfa Optima series, features the same big red Sensor shutter-release and large viewfinder as any other in the series, with some improvements and a built-in flash.
A CR-V3 battery (sometimes CRV3) is a type of disposable high-capacity 3-volt battery used in various electronic appliances, including some digital cameras. It has the shape and size of two side-by-side AA batteries. [1] This allows CR-V3 batteries to function in many (though not all) devices originally designed for only AA batteries.

An intelligent charger may monitor the battery's voltage, temperature or charge time to determine the optimum charge current or terminate charging. For Ni–Cd and Ni–MH batteries , the voltage of the battery increases slowly during the charging process, until the battery is fully charged.
The light energy emitted by a flash is supplied by the capacitor, and is proportional to the product of the capacitance and the voltage squared; photoflash capacitors may have capacitance in the range 80-240 microfarads (μF) and voltages from 180 to 330 volts for flash units built into small disposable and compact cameras, increasing for units ...
Video camera tubes are devices based on the cathode-ray tube that were used in television cameras to capture television images, prior to the introduction of charge-coupled device (CCD) image sensors in the 1980s. Several different types of tubes were in use from the early 1930s, and as late as the 1990s.
