20090244325 | Camera system, Camera body, Interchangeable lens unit, Focus control method, and Program - 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. | 10-01-2009 |
