摘要： An object of the invention is to provide a camera body of which a manual focus mode can be easily switched.A lens barrel includes an imaging optical system, a first operation ring, a second operation ring, and first and second sensors. The first sensor detects the rotation of the first operation ring and the rotation angle and the rotational direction of the first operation ring. The second sensor detects the angular position of the second operation ring. The imaging optical system includes a focus lens. A camera body includes a body control unit. The body control unit selectively executes a first manual focus mode in which the focus lens is moved according to the rotational direction and the rotation angle detected by the first sensor and a second manual focus mode in which the focus lens is moved according to the angular position detected by the second sensor.

摘要： According to an aspect of the present invention, the camera body can switch the present version, which is an original version, to specifications of an older version. Thus, even if the present versions of the camera body and the interchangeable lens doe not have compatibility, if an old version has compatibility, a minimum operation can be ensured by the specifications of the old version without updating the firmware, although the functions may have possibility of being restricted.

摘要： A shake correction control device includes a processor that selects mechanical correction of mechanically performing shake correction of a subject image or electronic correction of electronically performing the shake correction of the subject image. The processor performs a switching control from either of the mechanical correction or the electronic correction to the other of the mechanical correction or the electronic correction, and synchronizes shake correction operations of the mechanical correction and the electronic correction during the switching control, and changes an operation ratio of the mechanical correction and the electrical correction during the switching control.

摘要： A blur correction device includes a processor and a memory that is built into or coupled to the processor. The processor is configured to acquire an amount of blur correction used to correct blurring of an image obtained by imaging of an imaging element during exposure for one frame in the imaging element, and correct the blurring by performing image processing based on a most recently acquired amount of blur correction, on an unfinished image that is the image less than one frame that is being read from the imaging element. In a case in which a first reading period does not overlap with a second reading period, the processor corrects the blurring by performing the image processing based on the amount of blur correction acquired during exposure between the first reading period and the second reading period, on the unfinished image of the subsequent frame.
