A long-range optical sighting device includes a housing, which comprises an objective, an eyepiece, a reversing system and a target mark. The target mark illumination is switchable and controllable via an operating platform. The operating platform has one or a plurality of manually actuatable switches arranged on the housing in the region of the eyepiece, on the top of the housing in the operating position, and a power supply. Control electronics and a light-sensitive sensor system for detecting the ambient brightness are integrated in the operating platform and/or the housing in the region of the eyepiece. The operating platform comprises one or a plurality of light entrance openings for the light-sensitive sensor system in the direction of the objective.

Long-range optical sighting device having target mark illumination

An optical observation device for target acquisition and navigation having at least one objective, which is to be turned toward the object to be observed, and at least one ocular, which is to be turned toward the eye of the observer, in a housing, wherein the housing has at least one image reversal system, means for range finding, for location/position determination, for determination of the compass direction, and for displaying data, is distinguished in that an integrated target acquisition module having optoelectronic rangefinder, a GPS position determination, an electronic compass direction determination, and a microcomputer unit for calculating and storing distance and location coordinates of a targeted destination, an integrated navigation module having a display screen, which is arranged externally on the housing, and actuating elements, which are arranged on the housing, for activating functions of the target acquisition and navigation module are provided.

Optical observation device for target acquisition and navigation

A method for determining the current camera aperture (working aperture) of lenses on digital cameras having a viewfinder eyepiece and internal exposure measurement through the lens is wherein a further external exposure measurement is carried out past the lens and the value of the working aperture is determined from a reference table stored in the digital camera from the difference &#x394;BV between the two measured exposure values BV(int) and BV(ext). A digital camera suitable for carrying out the method wherein outside the region covered by the lens tube, the housing of the digital camera has an additional window for a further exposure meter with an upstream optics that is directed onto the subject and serves to restrict the shooting angle, and includes a memory for a reference table for determining the aperture value.

Diaphragm value recognition

An interchangeable lens connects in a prescribed position to a support surface on a camera of a camera system using a locking apparatus. A method and apparatus for identifying interchangeable lenses uses optical radiation. After the locking operation is performed, a defined optical radiation is directed from two or more, preferably six, light transmitters arranged in the support surface to reflecting or absorbing surfaces on the locking apparatus which are assigned to said light transmitters. The radiation returning from the respective reflecting/absorbing surfaces is picked up by light receivers arranged next to the light transmitters in the support surface. A binary coded signal for identifying the interchangeable lens is formed from the output signals of the light receivers.

Method and apparatus for identifying interchangeable lenses

An interchangeable lens () with a locking device (') for system cameras is described, wherein an orientation marking () for mounting the locking device (&#x2032;) on the camera is provided at the end of the lens housing () facing the camera, and the contact surface () of the locking device (&#x2032;) has a latching depression () at a distance from the orientation marking () counter to the direction () of rotation of the locking operation and the contact surface () contains at least two, preferably six, surface areas () which are situated next to one another in an isolated fashion at a distance from the latching depression () counter to the direction () of rotation within an angle segment of from 100&#xb0; to 160&#xb0;, preferably 110&#xb0; to 150&#xb0;, and can be detected individually by optical means.

Interchangeable lens with optically readable marking

A device for exposure metering in photographic cameras including a reflector located in the imaging beam path. The surface of the reflector is provided with a reflecting structure whose size corresponds at least approximately to that of the image recording format. At least one photoelectric receiver records the light intensity of a portion of the image reflected from the reflecting structure. The reflector is pivotally mounted in the camera housing such that during exposure metering the reflector surface is in the vicinity of the film plane of the camera. A limited portion of the reflector is transparent and a photoelectric receiver is set into the backside of the reflector behind the transparent portion.
