Image pickup apparatus

An image pickup apparatus comprising:

• an optical viewfinder;
• an electronic viewfinder;
• a viewfinder mode switching unit configured to switch between an electronic viewfinder mode in which a subject is observed with the electronic viewfinder and an optical viewfinder mode in which the subject is observed with the optical viewfinder;
• a first operation unit that can be set so as to inhibit a combination with the electronic viewfinder mode and that can be set so as not to inhibit the combination with the electronic viewfinder mode;
• a second operation unit that can be set so as to inhibit a combination with the electronic viewfinder mode and that can be set so as not to inhibit the combination with the electronic viewfinder mode;
• and
• a control unit configured to switch the electronic viewfinder mode to the optical viewfinder mode if the first operation unit is set so as to inhibit the combination with the electronic viewfinder mode in the electronic viewfinder mode, and configured to keep the electronic viewfinder mode and inhibit switching to the setting which is set by the second operation unit and in which the combination with the electronic viewfinder mode is inhibited if the second operation unit is set so as to inhibit the combination with the electronic viewfinder mode in the electronic viewfinder mode.

An image pickup apparatus comprising:

• an optical viewfinder;
• an electronic viewfinder;
• a viewfinder mode switching unit configured to switch between an electronic viewfinder mode in which a subject is observed with the electronic viewfinder and an optical viewfinder mode in which the subject is observed with the optical viewfinder;
• a first operation unit configured to indicate a state set by the position of a member that is operated;
• a second operation unit configured to indicate a state that is set so as to be irrelevant to the position of a member that is operated;
• and
• a control unit configured to determine whether switching to the electronic viewfinder mode is performed on the basis of a state set by the first operation unit if the switching from the optical viewfinder mode to the electronic viewfinder mode is instructed and, if the switching to the electronic viewfinder mode is performed, configured to forcedly change the setting set by the second operation unit to switch to the electronic viewfinder mode.

An image pickup apparatus comprising:

• an optical viewfinder;
• an electronic viewfinder;
• a viewfinder mode switching unit configured to switch between an electronic viewfinder mode in which a subject is observed with the electronic viewfinder and an optical viewfinder mode in which the subject is observed with the optical viewfinder;
• a first operation unit configured to indicate a state set by the position of a first operation member;
• a second operation unit configured to indicate a state that is set so as to be irrelevant to the position of a second operation member;
• and
• a control unit configured not to perform switching to the electronic viewfinder mode if the first operation unit is set so as to be inappropriate for the electronic viewfinder mode in the optical viewfinder mode, and configured to forcedly clear the setting which is set by the second operation unit and which is inappropriate for the electronic viewfinder mode to switch to the electronic viewfinder mode if the second operation unit is set so as to be inappropriate for the electronic viewfinder mode in the optical viewfinder mode.

An image pickup apparatus comprising:

• an optical viewfinder;
• an electronic viewfinder;
• a viewfinder mode switching unit configured to switch between an electronic viewfinder mode in which a subject is observed with the electronic viewfinder and an optical viewfinder mode in which the subject is observed with the optical viewfinder;
• a first operation unit configured to indicate a state set by the position of a first operation member;
• a second operation unit configured to indicate a state that is set so as to be irrelevant to the position of a second operation member;
• and
• a control unit configured to forcedly switch to the optical viewfinder mode if the first operation unit is set so as to be inappropriate for the electronic viewfinder mode in the electronic viewfinder mode, and configured to keep the electronic viewfinder mode and not to perform the setting which is set by the second operation unit and which is inappropriate for the electronic viewfinder mode if the second operation unit is set so as to be inappropriate for the electronic viewfinder mode in the electronic viewfinder mode.
