Depending on the mode Pluto Trigger is running, you should choose
different focus time.
For high-speed photography, fast response is critical. Your camera is set to
manual mode. You should choose “0-Manual focus” to tell Pluto Trigger no
need to focus before release shutter.
If you set your camera to Auto-focus mode and want the camera pre
focus before exposure, then choose appropriate focus time depending on
the light condition and your camera model. Please be noted in auto-focus
mode camera will not take picture if it doesn’t get focus. You are not
guaranteed to have your camera triggered in the mode.
In time-lapse mode of timer mode, you may like to put your camera into
sleep mode during the long interval to save a lot battery power. Then you
can set pre focus time to “0.5" - Pre Wake Up” in order to wake your
camera up before taking next picture.
