摘要： An interchangeable lens includes a drive unit that drives a focus lens back and forth along an optical axis, a storage unit that stores driving method information indicating a driving method for autofocus control which is supported by the interchangeable lens, a sending unit that sends the driving method information to the camera body, and a lens controller that controls an operation of the interchangeable lens. A camera body determines control on the interchangeable lens by referring to the driving method information obtained from the interchangeable lens to generate a control signal. The lens controller of the interchangeable lens controls the drive unit according to the driving method instructed by the control signal received from the camera body, when autofocus control is performed.

摘要： A camera system that can maintain a good focus state regardless of the speed of zooming during variable proportion zooming is provided. The camera system has a control portion that, based on information on the speed of the change in the focal length, determines whether to control a focus lens drive portion in either a first control mode or a second control mode. If it determines that control is to be performed in the first control mode, then the control portion controls the focus lens drive portion so that it drives a focus lens in the direction that brings a predetermined captured object into focus based on estimated values for auto focusing that have been calculated from the image data at various positions by controlling the focus lens drive portion so that the captured object distance is moved forward and backward in the optical axis direction. If the control portion determines that control is to be performed in the second control mode, then the control portion controls the focus lens drive portion based on a tracking table.

摘要： A camera body includes an imaging unit for generating image data from an optical signal incident via the interchangeable lens, a detector for detecting a light quantity of the optical signal, a controller for setting an aperture value of a diaphragm of the interchangeable lens and an exposure condition which is a setting relating to exposure other than a setting of the diaphragm, a sending unit for sending a control signal for control with the set aperture value to the interchangeable lens, and a mode setting unit for selecting one from a plurality of operating modes. The plurality of operating modes includes a first mode for automatically adjusting the aperture value of the diaphragm and the exposure condition according to the detected light quantity during capturing of a moving image, and a second mode for automatically adjusting the aperture value with the exposure condition being fixed according to the detected light quantity during capturing of the moving image. An average drive speed of the diaphragm for automatically adjusting the aperture value in the second mode is slower than that in the first mode.
