Camera body and imaging device controlling display based on detected mounting state of lens

A camera body to which an interchangeable lens unit configured to form an optical image of a subject can be mounted, the camera body comprising:

• a housing;
• a mounting component fixed to the housing, the mounting component to which the interchangeable lens unit can be mounted;
• an imaging element housed in the housing and configured to convert the optical image of the subject into an image signal;
• a display section configured to display the subject as an image on the basis of the image signal acquired by the imaging element;
• a mounting detector configured to detect the mounting state of the interchangeable lens unit with respect to the mounting component;
• a display controller that restricts the display of the subject as a live image on the display section when the mounting detector has detected that the mounting state of the interchangeable lens unit is incomplete;
• and
• a lens removal operating component configured to be operated to remove the interchangeable lens unit, wherein
• the mounting detector has a first detector configured to detect the state of operation of the lens removal operating component, and a second detector configured to detect that the interchangeable lens unit has been disposed at a specific position with respect to the mounting component, and
• the mounting detector detects the mounting state of the interchangeable lens unit with respect to the mounting component on the basis of the detection results of the first detector and second detector.
