AUTOMATIC FOCUSING CAMERA WITH MACRO LENS

PURPOSE:To eliminate an unrequired lens scan and to perform smooth focusing operation in automatic focusing adjustment with a macro lens by driving a photographing lens to a prescribed position on a short distance side when a subject is discriminated to exist on the short distance side shorter than a prescribed distance. CONSTITUTION:First of all, a distance is decided by first, second light flooding/ light receiving parts 13, 15, and a lens side micro computer (LCPU) 17 compares the quantity of a received light with that of a prescribed reference level, and discriminates whether or not the subject exists on the short distance side shorter than a prescribed distance, or whether or not the subject exists within a macrophotographing area, and transmits the discriminated result to a body side micro computer (BCPU) 21. Then, when the subject is discriminated to exist at no great distance, the photographing lens 1 is pre-driven, that is, driven to a position equivalent to the distance value of the prescribed short distance in advance. When no macrophotographing lens is used, no pre-drive is performed. Then, the LCPU 17 performs AF detection of a passive system by a ranging part 13 in a camera main body 2, and thus, when the deviation is found, the CPU 17 decides focusing.
