Abstract:
An image capturing apparatus includes: a photographing optical system; an image capturing element; and a viewfinder device, in which the viewfinder device includes at least one variable magnification lens that may be inserted on and removed from an optical path of the viewfinder device, and a drive mechanism configured to drive the variable magnification lens, in which the image capturing apparatus further includes: a variable magnification lens control unit configured to supply a drive signal to the drive mechanism so as to control the insertion and removal of the variable magnification lens on and from the optical path, and perform a high-speed control to move the variable magnification lens through a maximum moving distance for a first time, and a low-speed control to move the variable magnification lens through the maximum moving distance for a second time that is longer than the first time.
