Abstract:
1. An image-taking apparatus comprising: an image-pickup device for photoelectrically converting a subject image formed by light from an image-taking lens; a viewfinder optical system for enabling the subject image to be observed using the light; a focus detecting unit for detecting focus of the image-taking lens using the light; a mirror unit switchable between a first state and a second state to be switched, said first state being used to introduce the light into said viewfinder optical system and said focus detecting unit, and said second state being used to introduce the light to said image-pickup device and said focus detecting unit; and a controller for switching between said first state of said mirror unit and said second state of said mirror unit, and driving of a focus lens in the image-taking lens based on a detection result by said focus detecting unit, wherein a target driving position of the focus lens differs between said first state of said mirror unit and said second state of said mirror unit, wherein said controller prohibits the switching of said mirror unit while the focus lens is being driven.
