The Nikon 1 cameras are famous for being able to track focus with their on sensor PDAF.

But the story goes that if light is low, it will switch to contrast-detect only and will not track focus as effectively.

Does anyone knows at which point (in lux or EV levels) the Nikon 1 cameras switch focus mode and lose its high-quality track-focus capacities? (using either a kit lens or with the Nikon 1 18.5mm f/1.8).

In other words, at which light levels does focus-tracking works as advertised?

Your question is slightly misleading. Even in bright light the PDAF is only used to get the lens close to in-focus and then CDAF is used to do the fine adjustment. –  Michael Clark May 22 '13 at 17:52
That is what Canon does but I have never heard of Nikon doing this. Do you have a source for this statement? Nikon's article says it switches between systems not that it uses both together. –  Itai May 23 '13 at 15:13
I've e-mailed Nikon support with this question, they replied that they can not elaborate on it as it is classified information. So most probably you'll never find out... –  Bart Arondson Mar 13 '14 at 15:54
