PROBLEM TO BE SOLVED: To provide a single lens reflex camera capable of warning that there is the possibility of inappropriate photographing when the luminance and focused state of an object are drastically changed just before and after photographing. SOLUTION: The single lens reflex camera is provided with a main mirror which is moved between an object observing position and a photographing position, a light receiving means for receiving the luminous flux of the object reflected by the main mirror placed in the object observation position and obtaining exposure information, a focus detecting means for obtaining information on the focused state of a photographing optical system, and a control means for storing the exposure information obtained by the light receiving means just before a releasing operation and the focused state information obtained by the focus detecting means, and detecting the exposure information and the focused state information through the light receiving means and the focus detecting means again just after the releasing operation is finished, and then, comparing the exposure information and the focused state information just before the releasing operation with those just after the releasing operation, and for informing of the effect that there is the possibility of erroneous photographing in the case of deciding that either of the exposure information and the focused state information is not appropriate based on the comparison results. |
