摘要 <P>PROBLEM TO BE SOLVED: To provide a video camera system and a photographing method that can correct mis-focusing by the use of auxiliary light for auto-focusing even if using an interchangeable lens having a part of an auto-focusing function. <P>SOLUTION: The presence of light emission of auxiliary light for auto-focusing of a stroboscope 13 cannot be recognized on the interchangeable lens 50 side in using the interchangeable lens 50 having a part of the auto-focusing function. A signal of auxiliary light emission is therefore sent to the interchangeable lens 50 side from a camera microcomputer 11-1 of a camera body 60 to correct mis-focusing of auto-focusing by the use of auxiliary light (a red LED, 700 nm wavelength, or the like) by a lens microcomputer 14 of the interchangeable lens 50. <P>COPYRIGHT: (C)2009,JPO&INPIT
