History of the brand Hermagis New window

Traduction de Manuel M

The aspect of this new model of camera is that of a photographic jumelle camera of minimum volume for the same format; its weight, including that of 18 plates, is only of 1400 grams; it can be still more reduced by the use of films or the optional removal of an unspecified number of plates, precious advantage but exceptionally completed by the other systems, since the majority require, to work, a complete loading of the magazine.
As in Vélocigraphe 9 x 12 universally appreciate today by all connoisseurs, it is by means of a anchor escapement that the plates placed vertically one behind the other fall horizontally to the bottom of the darkroom after each exposure (fig. 3). The principle is thus the same one, and the advantages of the system prove by a long practice, by many testimonies, are not only preserved, but also increased.
We will restrict ourselves to summarize them as follows:
1° perfect and constant sealing, the retraction being made without drawer or slides likely to take game, to catch out or to be distorted.
2° regular functioning, free from failures, and rapid by means of one only key of operation which simultaneously produced the retraction, re-cocking, the rotation of the exposure counter and the chock of the fallen plates.
3° fast repetition (2 plates per second) essential for the interesting scenes which often follow with intervals often very closer (groups, attitudes, expressions, so fugitive as unexpected).
4° Impossibility of posing 2 times on the same plate, the shutter which cannot work if the exposed plate was not changed.
5° precise and instantaneous focusing for all distances from 2m ad infinitum, by means of the helicoids mount of the lens; the graduation of the marks is made on the lens hood which only make bulge of the camera.
6° Setting (for the 2 directions) not less precise and not slower by means of the new iconometer viewfinder kind of the Davanne viewfinder to reticulated divergent lens and blue glass making it possible to realize of the exact aspect that will have the finished exposure. The viewfinder takes seat in the thickness of the camera when one does not use of it.
7° optional and instantaneous pose 5 steps of speed of 1/20 to 1/200 of second by means of an eclipse shutter and of a release with double effect removing the cap.
8° fast unloading of the exposed plates without touching with those which are not it.
