摘要： A photographic camera of interchangeable lens type has an interchangeable objective that can be removably mounted on a camera body and a plurality of switches each capable of assuming a first or a second state. The switches all assume the same state when the objective is removed from the camera body and selectively assume the first and second states according to the value of at least one lens characteristic when the objective is mounted on the camera body. An automatic exposure control mechanism is operated responsive to the selectively assumed states of the switches when the objective is mounted on the camera body. A shutter release mechanism is disabled responsive to said same state of all the switches.

摘要： A control assembly and method are disclosed for providing manual stop-down mirror-up operations in a single lens reflex camera having a camera ready condition wherein an automatic diaphragm arrangement normally biases a diaphragm operating member to a full open position and a quick-return mirror arrangement normally biases a mirror to a viewing position. The control includes a button externally mounted on the camera for manual rotational movement between first and second button positions and for manual depressing operation in each of the button positions. In the first button position, depression of the button biases the diaphragm operating lever to a stop-down position with the mirror in the viewing position and release of the button returns the diaphragm lever to the normal full open position. In the second button position, depression of the button again provides the stop-down operation and also biases the mirror to a mirror-up shutter operating position. A button lock is provided at the end of the depression stroke in the second button position to retain the stop-down and mirror-up condition. The button lock is disengaged and the camera is returned to its camera ready condition upon manual rotational movement of the button to its first position.

摘要： A single lens reflex camera includes a separable view finder provided with a casing housing a pentaprism and electrical components. A set of laterally spaced contact pins depend from a shoulder in the casing forward of the pentaprism lower front surface and are connected to casing housed electrical components. The camera body also houses electrical components which are connected to resilient contact fingers mounted on the forward part of the camera body and underlying and releasably engaged by the contact pins. A slideable cover strip is spring urged to a position overlying the contact fingers and is retracted by the contact pins with the sliding coupling of the view finder to the camera body.
