Abstract

A camera-shake display device comprises a detection unit for determining whether a photographing lens detachably mounted on a camera body is provided with a compensation optical system for compensating camera-shake upon reception of a signal representing the camera-shake amount corresponding to a displacement of the camera body, and a display unit for displaying whether the camera-shake compensation is attainable or not in accordance with the output of the detection unit.

Claims

1. A photographing lens which is a part of camera system including a camera and the photographing lens detachably mounted on the camera, the camera system having a camera-shake detector to detect a camera-shake amount indicating a displacement of the camera system and to generate a signal representing the camera-shake amount, the photographing lens comprising:

a signal generator to generate a signal indicating whether said photographing lens has a compensation optical system to compensate camera-shake in accordance with the signal from said camera-shake detector,

said camera system being constructed to determine whether said photographing lens mounted on the camera is a camera-shake compensation lens based only on the signal from said signal generator, and to display, independently of occurrence of camera-shake, an indication which indicates whether said photographing lens is a camera-shake compensation lens.

2. A photographing lens detachably mounted on a camera having a camera-shake detector to detect a camera-shake amount indicating a displacement of a camera system including the camera and the photographing lens, and to generate a signal representing the camera-shake amount, the photographing lens comprising:

a signal generator to generate a signal indicating whether said photographing lens has a compensation optical system to compensate camera-shake in accordance with the signal from said camera-shake detector,

said camera system being constructed to determine whether said photographing lens mounted on the camera is a camera-shake compensation lens based only on the signal from said signal generator, and to display, independently of occurrence of camera-shake, an indication which indicates whether said photographing lens is a camera-shake compensation lens.

3. A photographing lens which is detachably mountable on a camera, of a camera system including the camera and the photographing lens, and which drives at least a part of a photographing optical system in a direction different from a photographing optical axis direction in accordance with a camera-shake signal to compensate the camera-shake, said photographing lens comprising:

a memory of information regarding the compensation driving; and

a signal interface for transmitting the compensation driving information to the camera,

said camera system being constructed to determine whether said photographing lens is a camera-shake compensation lens based only on the transmitted compensation driving information, and to display, independently of occurrence of camera-shake, an indication which indicates whether said photographing lens is a camera-shake compensation lens.
