Einrichtung an photograpischen Apparaten.
EMI1.1
bunden und ausserdem noch mit einem Fernrohrsucher ausgerüstet ist, ergeben sieh verschiedene Schwierigkeiten, wenn z. B. der Apparat von Brillenträgern benutzt wird oder wenn Aufnahmen gegen stark beleuchtete Schneelandschaften oder weisse Sandflächen gemacht werden müssen, weil bei Brillenträgern die Austrittspupille des Instruments infolge der Strahlengangverlegung durch die Brille nicht in der Augenpupille liegt und infolgedessen Fehlsichtigkeit eintritt.
Bei sein'hellen Landschaften wird das Auge durch den starken Lichteinfall geblendet, so dass eine Einstellung des Apparates sehr erschwert wird, oder durch die Verkleinerung des Bildes im Entfernungsmesser ist dasselbe nicht mehr scharf genug zu erkennen.
Die Erfindung bezweckt die Behebung dieser Schwierigkeiten, was dadurch möglich ist. dass die Einblicksöffnung des Suchers oder des Entfernungsmessers oder beide Einblicksöffnungen mit einem
EMI1.2
oder bei schwer erkennbaren Aufnahmeobjekten das Bild im Entfernungsmesser oder Sucher durch ein vorschaltbares Fernrohr vergrössert werden kann.
Die Zeichnung vera, nschaulicht den Erfindungsgegenstand in einer beispielsweisen Ausfihrungs- form in der Draufsicht, teilweise im Schnitt.

Establishment of photographic apparatus.
EMI1.1
bound and also equipped with a telescopic viewfinder, there are various difficulties when z. B. the device is used by people who wear glasses or if pictures have to be taken against heavily illuminated snowy landscapes or white sand surfaces because the eye pupil of people who wear glasses is not located in the eye pupil as a result of the beam path through the glasses and ametropia occurs as a result.
In his bright landscapes, the eye is dazzled by the strong incidence of light, so that it is very difficult to adjust the device, or the reduction of the image in the range finder means that it can no longer be seen clearly enough.
The invention aims to overcome these difficulties, which is possible thereby. that the viewing opening of the viewfinder or the range finder or both viewing openings with one
EMI1.2
or in the case of objects that are difficult to recognize, the image in the range finder or viewfinder can be enlarged using a telescope that can be connected upstream.
The drawing illustrates the subject matter of the invention in an exemplary embodiment in plan view, partially in section.
EMI1.3
Inlet openings for a fastening means is taken care of.
