CAMERA SYSTEM AND CAMERA BODY

摘要

In a camera system, it is possible to improve the user-friendliness of the monitor imaging mode. The camera system (1) includes an exchange lens (2) and a camera body (3). The camera body (3) has: an imaging unit (71), a contrast detection unit (31), a focal point shift amount detection unit (5), and a body microcomputer (12). The contrast detection unit (31) detects a contrast value from an image signal of an object captured by the imaging unit (71) and detects the focusing state of an optical image according to the contrast value. The focal point shift amount detection unit (5) detects a focusing state of the optical image by the phasedifference detection method. The body microcomputer (12) selects the contrast detection unit (31) or the focal point shift amount detection unit (5) according to lens information on the exchange lens (2) side.
