Menu Guide-The Setup Menu 4 Position the lens ten centimeters (four inches) from a bright, featureless white object. After framing the object so that nothing else is visible in the viewfinder, press the shutter-release button halfway. In autofocus mode, focus will automatically be set to infinity; in manual focus mode, set focus to infinity manually before pressing the shutter-release button. 5 Press the shutter-release button the rest of the way down to acquire Image Dust Off reference data (note that noise reduction turns on automatically when the subject is poorly lit, increasing the amount of time needed to record the data). The monitor turns off when the shutter-release button is pressed. If the reference object is too bright or too dark, the camera may be unable to acquire Image Dust Off reference data and the message shown at right will be displayed. Choose another reference object and repeat the process from Step 3. Dust ref photo SATw1lEePEa0hTnPXkcisTtemRPe.INOOpofhGrPSboojSRUmetoIRcNAtoETOfET Firmware Ver.
