Abstract

PURPOSE:To prevent the failure during photographing by substituting the correction signal during exposure correction with an electric signal, conducting this signal to the display element in the finder and distinctly displaying that it is now under correction. CONSTITUTION:To correct the exposure in photographing, the user rotates clutch members 4, 7 in the coupled state without lifting a film sensitivity index member 6, then the set value of the set film sensitivity changes and the exposure is corrected; at the same time, a supporting member 11 for exposure correction is rotated by a protruding part 15 along with the rotation of an external display member 3; therefore, its contact piece 13 closes the circuit emitting the exposure correction signal on a wiring board 16, the electric signal generated by which ables the display element 18, such as light emitting diode or liquid crystal, in a finder visual field 17 whereby the exposure correction is displayed in the finder.
