To complement the speed of the f1.8 lens, the camera's low-light mode automatically adjusts the ISO sensitivity up to ISO 12, 800 to take sharp, full-resolution photos in dim conditions, and an easily accessible built-in pop-up flash and AF illuminator brightens low-lit subjects, reduces red-eye and fills in dark areas.
For maximum runtime the switch is held down for ten seconds, activating the light in dim mode and producing a mild 1.3 lumens of light with an extreme runtime of 480 hours.
