Thanks all. Trench... I usually shoot pretty wide open too but when I shoot with studio strobes & stop it down and there's a plain background, oh boy! It's a mess like my old D1x. The D300 is as clean as a whistle. It's a little disconcerting to have a feature on the camera that gives me no evidence of working.
NPS usually defers tech questions to Nikon USA who wrote "If you go into setup options, you will see two options for cleaning the sensor, one is clean now, the other is to clean at start-up or shut-down." Okay...
