Claims

[Claims for Utility Model Registration] Consisting of a camera body and a photographing lens that is replaceably mounted on the camera body, the camera body is configured to change the state of the subject image formed by passing through the photographic lens into the lens. a first defocus amount detecting means for detecting the defocus amount; and a first defocus amount detecting means for transmitting the detected defocus amount to the lens side.
The photographic lens includes a transfer means, a focus motor that drives the focus lens, and a control means that controls the motor, and the photographic lens includes a storage means that stores lens-specific information, and a defocus amount and information that is transferred from the body. It is characterized by comprising a calculation means for calculating the drive amount of the focus motor based on the information stored in the storage means, and a second transfer means for transmitting the calculated number of drive pulses to the control circuit of the camera body. A single-lens reflex camera system.
