SINGLE LENS REFLEX CAMERA AND FINDER EQUIPPED WITH FOCUS DETECTION SENSOR HAVING FUNCTION TO DECIDE NECESSITY OF CALIBRATION

摘要

PROBLEM TO BE SOLVED: To provide a single lens reflex camera equipped with an interchangeable type finder capable of performing calibration for accurately detecting the amount of out-of-focus without forgetting it, and displaying whether or not the calibration should be performed.;SOLUTION: This single lens reflex camera has a camera body having a focusing screen provided with a reference mark corresponding to the position of film, the finder detachably attached to the camera body, a focus detection means which is arranged in the finder and detects a focal position, a deviation detection means which is arranged in the finder and detects the deviation of the focal position from the reference mark, a calibration means for correcting data on the focal position based on output from the deviation detection means, a storage part for storing correction amount calculated by the calibration means, an attachment/detachment detection means for detecting the attachment/ detachment of the finder, and a calibration deciding part for deciding whether or not the calibration is required based on information acquired by the attachment/detachment detection means.;COPYRIGHT: (C)2002,JPO
