1. A camera system including an interchangeable lens having an optical correction means for optically correcting an optical axis varied by a shake and a camera to which the interchangeable lens is to be installed, wherein:
the camera includes:
a first reception means for receiving current-position information based upon and indicative of a correction angle of said optical correction means within a range of angles permitting optical correction;
an angular shift detection means for outputting angular shift information regarding an imaging angle of said camera varied by the shake;
an optical-correction angle information calculation means for calculating optical-correction angle information including information based on a maximum correction angle for the interchangeable lens to be conveyed to said optical correction means based on the current-position information and the angular shift information,
wherein the optical-correction angle information calculation means includes a centering unit for adjusting the optical-correction angle information so that the optical-correction angle information is within a range of angles that can be corrected by the optical correction means; and
a first sending means for sending the optical-correction angle information to the interchangeable lens, and
the interchangeable lens includes:
a second reception means for receiving and inputting the optical-correction angle information to said optical correction means; and
a second sending means for sending the current-position information of said optical correction means to said camera; and
said optical correction means optically correcting the optical axis so that the current-position information may approach a control target value provided by the correction angle information.
