Low light focussing with 70-200 2.8

I just got this lens a couple of weeks ago to use with my D800. I was shooting with it in North Carolina and had no trouble even at dusk. However, I was shooting in basement the other night with two modelling lights on (low power) and the lens could rarely find the focus. Then I switched to the 24-120 F 4.0 lens-pretty much the same settings (F8 or F11, 1/200 shutter speed) and and light conditions and it found focus every time. I'm just wondering why the 70-200 had so much trouble or was I doing something wrong or is there a setting I need to change.

Thanks,
