Abstract

In a camera system where a taking lens and a camera body respectively comprise a image shake correction unit for correcting a shake, which occurs on an image on an image capturing surface due to a jiggle of the camera system at the time of shooting, the taking lens and the camera body respectively comprise a communication unit for making a communication between the taking lens and the camera body, and a control is performed so that the communication unit of the camera body transmits a lens operation suspension instruction when the image shake correction unit of the camera body is operated, and the operation of the taking lens is suspended when the communication unit of the taking lens receives the lens operation suspension instruction.

Claims

1. A camera system where a taking lens and a camera body respectively comprise a image shake correction unit for correcting a shake, which occurs on an image on an image capturing surface due to a jiggle of the camera system at the time of shooting, wherein:

the taking lens and the camera body respectively comprise a communication unit for making a communication between the taking lens and the camera body; and

a control is performed so that the communication unit of the camera body transmits a lens operation suspension instruction when the image shake correction unit of the camera body is operated, and an operation of the taking lens is suspended when the communication unit of the taking lens receives the lens operation suspension instruction.

2. The camera system according to claim 1, wherein

a control is performed to suspend at least driving of a focus lens and an operation of the image shake correction unit of the taking lens, when the communication unit of the taking lens receives the lens operation suspension instruction.

3. The camera system according to claim 1, wherein

a control is performed to suspend at least an operation of the image shake correction unit of the taking lens, when the communication unit of the taking lens receives the lens operation suspension instruction.

4. The camera system according to claim 1, further comprising:

a lens anti-shake switch for setting validity/invalidity of the image shake correction unit comprised by the taking lens;

a body anti-shake switch for setting validity/invalidity of the image shake correction unit comprised by the camera body; and

an anti-shake selection processing unit for selecting, with higher priority, any one of the image shake correction units of the taking lens and the camera body according to settings of the lens anti-shake switch and the body anti-shake switch, wherein

a control is performed to operate the image shake correction unit of the camera body, when the image shake correction unit of the camera body is selected by the anti-shake selection processing unit.

5. The camera system according to claim 1, wherein

the lens operation suspension instruction is transmitted prior to a start of exposure.

6. The camera system according to claim 1, wherein

a control is performed to suspend an operation of the taking lens within a predetermined amount of time shorter than a release time lag of the camera body, when the communication unit of the taking lens receives the lens operation suspension instruction.

7. The camera system according to claim 1, wherein:

the lens operation suspension instruction includes information of a suspension time until an operation of the taking lens is suspended; and

a control is performed to suspend the operation of the taking lens within the suspension time, when the communication unit of the taking lens receives the lens operation suspension instruction.
