Abstract
Provided are a camera system, an interchangeable lens, a camera, and a power supply method of a camera system capable of simplifying a configuration. In a camera system () comprising a camera () and an interchangeable lens (), a plurality of pieces of lens-drive power (VLto VL) having different voltages are supplied from the camera () to the interchangeable lens (). The interchangeable lens () drives a plurality of optical member drive units such as a focus drive unit and a stop drive unit using the plurality of supplied pieces of lens-drive power (VLto VL). Further, system power for operating a lens microcomputer () is generated using the lens-drive power (VL) having the lowest voltage among the plurality of supplied pieces of lens-drive power (VLto VL).
