Claims

[Scope of Claim for Utility Model Registration] Defocus amount detection means for detecting the amount of lens defocus from the state of a subject image formed by passing through an interchangeably mounted photographic lens; and the amount of drive of the focus lens based on the defocus amount. a motor driving means for driving and controlling the focus motor based on a focus motor that drives the focus lens and the drive amount; a first selection means for selecting whether to drive the focusing lens by the focus motor or a motor within the lens; and when the first selection means selects the drive by the motor within the lens; A single-lens camera characterized by comprising a second selection means for selecting whether to transfer the defocus amount or the drive amount to the lens side as autofocus information to the lens side in accordance with second information from the photographic lens. Camera body of reflex camera.
