摘要： An exposure time controlling system includes a circuit for producing an APEX shutter speed signal which is applied to a first discriminator for briefly classifying the APEX shutter speed signal into four classes and also to a second discriminator for sub-classifying the APEX shutter speed signal. A pulse generator is provided for producing pulse signal having a frequency determined by the class and a counter is provided for counting the pulses for a number of times determined by the sub-class. A shutter mechanism is opened when the counter starts to count and is closed when the counter finishes counting the pulses.

摘要： A camera system with an auto-focusing system includes a camera body and an interchangeable zoom lens. The interchangeable objective lens stores various data to be sent to the camera body for improving automatic focus adjustment, such as an information necessary to convert the detected defocus information into a movement of the driving power source to carry out the automatic focus adjustment. The driving power source in the camera body is controlled in responses to the data from the interchangeable objective lens and the detected focus information, the driving power being transmitted to the interchangeable objective lens. The camera body is further capable of inhibiting the focus adjustment or focus indication in response to a data from the interchangeable objective lens under an unfavorable condition.

摘要： An auto-focusing system includes a focus condition detector which detects the focus condition based on infrared light. A data producer is provided for producing a deflection signal indicating the difference between an image forming distance for infrared light and that for visible light, due to aberration. In accordance with the detected focus condition and deflection signal, an objective lens is shifted to a position for properly focusing an image of visible light on an image forming plane.
