You are certainly right Brian, Sorry Dennis, I guess I thought by ommission that it wouldn't change the ISO in manual mode. So I just got out my D700 set it to manual mode, shutter speed 160, aperture f2.8, auto ISO on, minimum shutter speed 1/30 second,( I don't think it matters on shutter speed in manual mode just telling you my settings), maximum sensitivity 3200. I pointed my camera at the kitchen light, at those settings it gave me a neutral reading, as I moved the camera away the sensitivity whent up to keep the exposure correct untial it reached the maximum. Hope This helps.
