The Standard is a coupled rangefinder camera for 35 mm film, made by Industria Scientifica Ottica in Milan, Italy, in about 1953. The camera was also sold by the German company Hensoldt as the Henso Standard.
An article on ISO cameras at Fotocamere Italiane calls the Standard a simplified model of the Bilux, and states that a protoype of it, called the Junior, was produced. Certainly, the Standard is very similar to both the Bilux, which preceded it, and the Reporter which came after it.
The simplifications are significant:
- Whereas the Bilux has both a conventional winding knob and a trigger mechanism to advance the film, the Standard only has the winding knob.
- The Standard has no slow shutter speed control: the shutter offers speeds from 1/20 to 1/1000 second, plus 'B'.
- The Standard has two PC sockets, for M- and X-synchronisation, instead of the single socket and adjustable synchronisation delay of the Bilux.
- The Standard does not have a film-type and speed reminder dial.
The standard lens is a collapsible 5 cm f/3.5 Iadar, f/2.8 Iriar or f/2.8 Arion, or a rigid f/1.9 Arion. The camera will accept the same interchangeable lenses, (some or all made by Hensoldt) as the Reporter; there is an 8 cm f/2.5 Aglar and a 12.5 cm f/3.5 Iriar. SOM Berthiot also made a 28 mm f/3.3 Angulor for the Standard and Reporter.
The camera has an interchangeable viewfinder eyepiece, to allow a different one to be fitted for each focal length. It has a knurled focusing wheel on the front of the body, like the Contax rangefinders, operated with the right index finger.
