a7 Built-in AF Assist Illuminator
Explanation: With the standard setting „on“ the little lamp called
AF-Assist Illuminator between flash and shutter release button will lighten up if the ambient light is weak and the autofocus is set as follows:
- No continuous autofocus, i.e. either autofocus is set to AF-S or it is set to AF-A and has not recognized a moving subject
- Focus point selection is either automatic or manually with the center focus point selected.
Tips: The autofocus works well also in low light. If you find the light disturbing because it can distract people just give it a try without. In many situations where the D7000 switches on the lamp it will still be able to focus without.
