<p>PURPOSE:To make selection of photographing modes smooth and easy by dividing the finger-touch surface of a shutter button to two regions corresponding to the open and close of a touch switch. CONSTITUTION:When the middle finger of the right hand is contacted to the bisected region 6a or 6b of a shutter botton and is depressed, a touch switch SW1, closes only when the region 6a is depressed. Then the output of an invertor 1 inverts to a high level, putting a shutter speed device S1 for aperture priority in an operation state. On the other hand, when the switch SW1 is open, an aperture control device A1 for shutter priority to which the high level output is applied assumes an operation state, thus the photographing modes may be smoothly changed over by the easy operation. Similarly, various photographing modes such as program mode, manual mode, etc. are selected.</p> |
