Camera system and interchangeable lens

Abstract

The present invention provides an interchangeable lens mounted on a camera body in an exchangeable manner, and the interchangeable lens includes: an optical system in which a state of a subject light flux incident to the mounted camera body is adjustable by changing an optical state; a contact position detecting unit with a detection plane, which detects a contact state including a contact and a contact position of a finger of a photographer, to detect a change in a contact position on the detection plane in an approximately same direction as an optical axis direction of the optical system; and a lens controller to control an optical state of the optical system according to a contact state of the finger including the contact position detected by the contact position detecting unit.

Description

technical field [0001] The present invention relates to camera systems and interchangeable lenses. Background technique [0002] In recent years, imaging equipment has been significantly improved, and in the field of cameras, photographic functions have increased year by year, and functions operable by photographers have also increased, and various methods have been proposed for operating functions. For example, an operation method related to a preset operation of driving a focus lens or a zoom lens in an interchangeable lens to a predetermined position registered in advance by operating a button or a dial provided on the interchangeable lens as disclosed in Patent Document 1 has been proposed. , or as disclosed in Patent Document 2, a touch sensor is provided instead of the manual focus ring provided on the outer peripheral portion of the general interchangeable lens barrel, and the finger is detected based on the moving direction, moving amount, and moving speed of the fin...

Problems solved by technology

[0009] In the case of the manual focus operation of the touch sensor disclosed in Patent Document 2, there is little possibility of operation noise during movie shooting, but the lens is controlled by the amount or speed of movement of the finger on the touch sensor on the outer periphery of the lens. The operation of the drive requires great skill, and if the operation is not performed properly, the focus will change unnaturally and the quality of the image will be damaged.

In addition, still image photography may also cause a lot of pressure to manually focus if you are not skilled.

In the case of the operation restrictions when the viewfinder is close to the eyes disclosed in Patent Document 3 and Patent Document 4, the items that need to be operated may be limited according to the photographer. In addition, even if the operation is possible, it is only when the viewfinder is close to the eyes or around the face. There is a technical problem of poor grip and operability of the camera due to the operation of moving fingers between the camera and the camera.
