LENS INTERCHANGEABLE TYPE CAMERA, INTERCHANGEABLE LENS, AND CONTROL METHOD FOR LENS

摘要

A lens interchangeable type camera system, comprising an interchangeable lens and a camera body, comprising a first control section that carries out manual focus control by detecting rotation direction and rotation amount of an operation member, in accordance with a manual focus mode command from a mode setting at a time when the operation member is at the first position, and a second control section that, when the operation member is at a second position, irrespective of a command from a mode setting section, notifies a detection result of a first detection section to the camera body, detects rotational position of the operation member using a third detection section, and forcibly carries out manual focus control based on a rotation position, wherein the lens interchangeable type camera system further comprises a function restriction section that sets operation of the second control section to valid or invalid.

主权项

1. A lens interchangeable type camera system, comprising an interchangeable lens and a camera body to which the interchangeable lens can be attached,
the camera body comprising: a mode setting section that switches between auto focus and manual focus, the interchangeable lens comprising: an annular operation member, arranged outside the interchangeable lens, that is capable of sliding to a first position and a second position in the optical axis direction, a first detection section that detects position of the operation member, a second detection section that detects rotation direction and rotation amount of the operation member at a time when the operation member is at the first position as a result of a slide operation, a third detection section that detects rotation position of the operation member at a time when the operation member is at the second position as a result of a slide operation, a first control section that carries out manual focus control by detecting rotation direction and rotation amount of the operation member using the second detection section, in accordance with a manual focus mode command from the mode setting at a time when the operation member is at the first position, and a second control section that, when the operation member is at the second position, irrespective of a command from the mode setting section, notifies a detection result of the first detection section to the camera body, detects rotational position of the operation member using the third detection section, and forcibly carries out manual focus control based on the rotation position, wherein the lens interchangeable type camera system further comprises a function restriction section that sets operation of the second control section to valid or invalid.
