3 Custom Function Settings Shutter release time lag Normally, the shutter release is controlled for a stable release time lag. By setting [Shortened], this stabilization control can be omitted to make the shutter-release time lag shorter. Standard Shortened The normal shutter-release time lag is approx. 0.055 sec. when the aperture is stopped down by no more than four stops (depending on the lens). When set to Shortened, the shutter-release time lag is approx. 0.036 sec. At the maximum aperture, the shutter-release time lag will be approx. 0.036 sec. regardless of the lens. The Shortened shutter-release time lag will vary depending on the lens and aperture setting. Memo audio quality You can set the audio quality when you record a voice memo. 48kHz: High quality (48 kHz) You can record the voice memo at the same audio quality as a movie. 8kHz: Low quality (8 kHz) The voice memo's file size is smaller than with [High quality (48 kHz)]. If you record another voice memo to an image which already has a voice memo, the audio quality will be the same as the first voice memo regardless of this setting. Default Erase option During image playback and image review after image capture, when you press the button, the Erase menu appears (p.284). You can set which option, [Cancel] or [Erase], is to be preselected on this screen. If [Erase] is set, you can just press to quickly erase the image. [Cancel] selected L [Erase] selected If [Erase] is set, be careful not to erase an image accidentally. 336
