ABSTRACT:
An automatic focusing camera including a camera body and a photographing lens detachably mounted to the camera body. The camera body includes a focus detecting device which outputs a focus signal in accordance with an image formed by a photographing lens, an auxiliary light emitter for emitting auxiliary light for detecting the focus, and an arithmetic operating device for calculating data on focus in accordance with the focus signal output from the focus detecting device, The photographing lens includes a memory for storing predetermined lens data, and an outputting device for outputting the lens data to the camera body. The memory stores correction data on the focusing condition when the auxiliary light is emitted from the auxiliary light emitter. The arithmetic operating device calculates the data on the focusing condition in accordance with the detection data of the focus detecting device and the correction data input from the photographing lens.
