PURPOSE:To enable shutter release after automatic focusing to be accomplished arbitrarily by providing a changeover device and enabling automatic focusing operation and shutter release operation to be accompoished either continuously or independently. CONSTITUTION:Now, when a changeover switch 11 is released and a release lever 1 is pushed down, the protrusion 1a of the release lever disengages a charge-ring- detaining ring 2. Then, a charge ring 3 turns right to complete automatic focusing then closes the first switch 9. However, a shutter operating circuit 8 does not operate and no shutter release is accomplished because the changeover switch 11 and second switch 10 are both open. Thereupon, changing of framing is performed. Next, when the release lever 1 is further pushed down, the protrusion 1b of the release lever 1 closes the second switch 10, by which shutter release is effected. In this way, the shutter release after the automatic focusing may be accomplished as desired. |
