Abstract
A camera has a first photographing mode for also performing a second photographing operation at a focusing-lens position of a first photographing operation, a second photographing mode for performing autofocusing for every photographing operation, and diaphragm controller for controlling the amount of an aperture of a diaphragm. The diaphragm controller maintains the diaphragm in a state at the first photographing operation when the first photographing mode is selected, and returns the diaphragm to a predetermined position for every photographing operation when the second photographing mode is selected.
Claims10
A camera comprising:
- (a) a specific photographing mode for performing plural photographic operations by shifting a stop value of a diaphragm by a predetermined amount;
- and
- (b) diaphragm control means for driving the diaphragm, without driving the diaphragm to a full open position between successive photographing operations, by an amount of a shift of the stop value of the diaphragm from the stop value at the preceding photographing operation, in a condition that the specific photographing mode has been selected.
A camera body to which an interchangeable lens incorporating a diaphragm can be detachably mounted, said camera body comprising:
- (a) a specific photographing mode for performing plural photographic operations by shifting a stop value of a diaphragm by a predetermined amount;
- and
- (b) diaphragm control means for driving the diaphragm, without driving the diaphragm to a full open position between successive photographing operations, by an amount of a shift of the stop value of the diaphragm from the stop value at the preceding photographing operation, in a condition that the specific photographing mode has been selected.
A camera comprising:
- (a) a specific photographing mode for performing plural photographic operations by shifting a stop value of a diaphragm by a predetermined amount;
- and
- (b) diaphragm control means for driving the diaphragm, in a condition that said specific photographing mode has been selected, from a first position directly to a second position, the first position differing from the second position by an amount of a shift in stop values between successive photographing operations.
