description A camera provided with an automatic focusing device which automatically detects the focus condition of an objective lens and driving the objective lens towards an in-focus position in response to the manual operation to a shutter release button. The operation of the automatic focusing device is actuated by a switching means when the shutter release button is touched by a user's finger or is depressed down after the touching. When the shutter release button is further depressed beyond the first stroke, the operation of the automatic focusing device is inhibited once an in-focus condition is obtained.
