Zeiss Ikon Icarex 35 CS.
The shutterEither mechanical and/or electronic shutters are possible. Mechanical systems can use a leaf (or iris) shutter or curtain shutter. In digital cameras a third alternative is also possible: the electronic shutter. This works by activating and then deactivating the CCD so that no further light can be recorded, regardless of whether light is hitting the CCD. The shutter controls the exposure time, which can range from thousandths of a second to several minutes or more. Fast shutter speeds freeze action, slow speeds are more suited to stationary subjects. A tripod is recommended for slow exposure shots to avoid camera shake, or IBIS. More fires and the camera looks quite clean and functional.
The prism can be removed and houses the meter. I have not tested the meter a I do not have the right battery. I do not think it will work as the top dials appear to be seized.
This version has a Bayonet Mount Lens. F2.8 50mm Carl Zeiss.
