 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.

 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.

 Inlet openings for a fastening means is taken care of.
