(57) [Summary] [PROBLEMS] To provide a camera with interchangeable lenses that does not cause a distance measurement error. SOLUTION: When a manual focus mode, an auto focus operation, and a switching macro are not set when a switch S1 is on (S234, S235, S (NO in 236), first perform "distance measurement synchronization" communication to output an integration time lag, and input data as to whether or not the lens speed is stable (S239). If the lens speed is stable, CCD integration is performed (S240). |
