Patent ID: 7057644

Claim:
A camera system including a camera and a lens apparatus detachable from the camera, comprising: a communication circuit which communicates data between said camera and said lens apparatus; a vibration detector provided in said camera, which detects a camera shake; a camera control circuit provided in said camera, which calculates vibration correction data based on an output from said vibration detector and sends the calculated vibration correction data to said lens apparatus through said communication circuit; a vibration correction optical member provided in said lens apparatus, which is driven for correcting an image vibration; a vibration correction driving unit provided in said lens apparatus, which drives said vibration correction optical member; and a lens control circuit provided in said lens apparatus, which controls said vibration correction driving unit based on the vibration correction data sent from said camera through said communication circuit; wherein, said camera control circuit sends said vibration correction data with a first data length to said lens apparatus during an image-taking operation of said camera and sends said vibration correction data with a second data length shorter than said first data length to said lens apparatus during an image-taking preparation operation of said camera; and wherein said lens control circuit controls said vibration correction driving unit based on said vibration correction data with said first data length sent from said camera, converts said vibration correction data with said second data length into data equivalent to said vibration correction data with said first data length and controls said vibration correction driving unit based on the converted vibration correction data.
