The Pentacon Six System
The History of the Pentacon Six
The Pentacon Six
Dates: 1966 or 1967-1969 – CB
A Pentacon Six with a Biometar lens from November 1965 that was probably
made before the camera, but may have been sold with it.
In this picture one can see the film type and speed reminder dials
on the shutter speed dial and the frame advance lever, respectively.
It is also possible to see the perspex cover on the frame counter,
and the flash synch cable locking nut (just under the lens, at “7.00 o’clock”).
This camera incorporated a number of significant changes:
With this model there was a major improvement in film transport
(spacing), with the incorporation of a spindle with serrated teeth inspired
by the sprocket wheels or spindle of 35mm cameras. This measured
the amount of film being advanced and works well if the film is loaded
It was now possible to use 220 film (24-exposures) as well
as 120 (12-exposure) film. An automatic advance lock after the 12th
and 24th frame made the user aware of the end of the film.
The frame counter automatically reset on opening the camera
back, so the counter re-set button was no longer needed.
The frame counter was covered by a larger but flatter Perspex
Film type and speed reminder dials disappeared from the camera
back and were placed on the shutter speed knob and the advance lever respectively.
The two screws that hold the “removable” back in place were
now anodised black instead of the chrome of all the preceding models: the
idea of supplying different backs seems to have been abandoned.
There was no longer an “X” by the flash socket, it presumably
having been decided that this would be the only type of flash synchronisation
that was required (at least within Europe).
There was a locking nut for the flash synch cable.
Inside the Pentacon Six
The spindle that controls film spacing is arrowed.
Two non-blackened springs on the door help to press the film against
Another spring in the film feed chamber on the left also helps to hold
the film tight,
to ensure both accurate spacing and good film flatness.
Accessories and lenses
This Pentacon Six is fitted with the standard 80mm Biometar lens in
the so-called “zebra” style. The lens in this picture was completed
on 29th March 1968 and was probably sold with this camera.
||A fresnel viewfinder lens became available as an option.
This increased viewfinder brightness fourfold (equivalent to two extra
stops on the objective lens).
There were now automatic aperture lenses up to 300mm (with
the introduction of the 300mm Zeiss Sonnar in 1966).
