Of the many arrangements that would go too far to explain here, there were also those that placed the entire transport between the two cassettes and provided the lens changing mechanism and the front or rear shutter.
This gave rise to the type that can be described as symmetrical. A channel for viewing the magnifying glass can be placed between the cassettes so that the image can be viewed on the film during the recording.
The symmetrical arrangement offers a whole range of other advantages, and it is understandable that this type of construction is chosen at the start of the production of the cinema camera.
Taking into account all the practical experience of the cameramen and using high quality materials and the finest mechanics, the Askania movements have succeeded in creating a device that is not only of the highest level in terms of construction, but also in terms of mechanical design.
The camera has not only proven itself in practice, but has also achieved successes that show that all requirements set for such a camera are fully met.
We find this cine camera not only widespread in professional circles, but especially in those cases where (in which) most constructions have failed, it was a great success.
The camera has never failed on several expeditions to Japan, India and the African jungle. Colin Roß used them on his world tour, Schomburgk brought the most beautiful films from the African jungle, and this camera type was the first and only one in the R.Z.III (that was the airship of Hindenburg) to find its way to America.
