3 Reducing FlickerK If you shoot an image with a fast shutter speed under a light source such as fluorescent light, the blinking of the light source causes flicker and the image may be vertically unevenly exposed. If continuous shooting is used under these conditions, uneven exposures or colors across the images may result. With anti-flicker shooting, the camera detects the frequency of the light source's blinking and takes the picture when the flicker causes less effect on exposure or color. 1 Select [Anti-flicker shoot.].  Under the [z3] tab, select [Antiflicker shoot.], then press . 2 Select [Enable].  Select [Enable], then press . 3 Take the picture.  The image will be taken with reduced unevenness of exposure or color caused by the flicker.  When [Enable] is set and you shoot under a flickering light source, the shutter-release time lag may become slightly longer. Also, the continuous shooting speed may become slightly slower, and the shooting interval may become irregular.  This function does not work with Live View shooting and movie shooting.  In the or mode, if the shutter speed changes during continuous shooting or if you shoot multiple shots of the same scene at different shutter speeds, the color tone may be inconsistent. To avoid inconsistent color tones, use the or mode at a fixed shutter speed.  The color tone of images shot when [Anti-flicker shoot.] is set to [Enable] may look different from when [Disable] is set.  Flicker at a frequency other than 100 Hz or 120 Hz cannot be detected. 144
