摘要： A automatic focus detecting apparatus in which a focal point position corresponding to a change in position of an object after the elapse of a predetermined time is foreseen and calculated on the basis of the result of a past focal point adjustment. In accordance with the aperture value and lens characteristic at the time of photographing, a selection is made with respect to whether the calculation is executed in a normal mode to calculate the focal point position on the basis of only the result of the detection of the focal point at the present time independently of the result of the past focal point adjustment, or the calculation is executed in the foreseeing mode. Upon photographing, if there is no need to execute the foreseeing calculation, the focal point position is calculated in the normal mode.

摘要： A camera including an imaging optical system and a focus detecting circuit for repeatedly performing a focus detection operation and outputting a focus signal representing the focusing state of the optical system at the time of each focus detection operation. A calculation circuit predicts, on the basis of previous and latest focus signals, the focusing state of the optical system a predetermined period of time after the detection of the latest focus signal. The predetermined period of time includes a shutter release time-lag. A driving circuit drives the optical system by an amount corresponding to the focusing state calculated by the calculation circuit. A releasing circuit begins a film exposure in response to the operation of a shutter release member. A release timing control circuit controls the releasing circuit so that it does not operate until a point of time which is earlier, by an amount equal to the release time-lag, than the predicted time.

摘要： A camera with a mirror device comprises a first mirror, i.e., a main mirror, device for reflecting object light, and a second mirror, i.e., a sub-mirror, device for reflecting light transmitted through the first mirror device to another device, i.e., a focus detector. The second mirror device has a reflective layer formed as a sub-mirror surface formed directly on a base member. With the sub-mirror surface formed by, e.g., evaporation directly on a partial protruded area of the base member, the manufacture process is facilitated, a sub-mirror area can be increased, and reliability and durability are improved because the sub-mirror will not experience variations in its mounting angle or be subject to peeling-off from a separate base member.
