vintage EXA 1b camera + Carl Zeiss 2.8/50 lens
Mooie en goed werkende camera uit de voormalige DDR (Pentacon) met Carl Zeiss lens. Typisch voor deze camera is de viewfinder die bovenop is gemonteerd en (!) in spiegelbeeld werkt. De camera zit in een (we denken niet originele) beschermhoes van Pentacon.
Mooi dingetje nog!
The Exa 1b is a 35mm film SLR camera, manufactured by VEB Pentacon, former East Germany, and produced between 1977-85. It is a continuing model of the long lasting Ihagee Exa series by Pentacon.
VEB Pentacon licensed the production of screw-mount Exas to Certo Camera Werk, Dresden-Großzsachwitz, a part of VEB Pentacon. Cameras built by Certo have serial numbers preceded with a letter C. Some late Exa 1b version 4.4 and all Exa 1c version 4.5 made by Certo.  The later models of Exa 1b have black plastic top- and bottom plates.
Exa 1b body is virtually identical to Exa Ia except rewind knob replaced with a crank and the lens mount is M42, instead of the traditional Exakta bayonet mount. The camera also has internal aperture coupling for M42 automatic lenses.
Exa 1b uses most standard Exakta viewfinders, waist-level and prism. Standard lens is Meyer Domiplan, other main lenses are Tessar, Makinon and Super Takumar.
Exa 1b is not a real part of the Exakta/Exa system, although its family relationship with Exa cannot be denied. Exa 1b renamed as Exa 1c without practically any other changes.
There are 4 versions of the Exa 1b according to Andrzej Wrotniak

There is a standard M42 type arc/lever on the body, that depresses the pin on the lens that closes the diaphragm blades. When the pressure is let up, the lens opens fully again. A half-depression of the shutter release allows a depth of field preview.
