I took a short walk in the neighborhood tonight with the D80, this time with the 50mm f/1.8, thinking the extra stop would be useful as the light faded. As shutter speeds started dropping below what I can hand hold, particularly on a walk when I pause and shoot, I put the on camera flash into action. I dialed the flash compensation down by between 1.5 and 2.5 stops. It was enough to isolate foregrounds in the light and bring the shutter speed up to 1/30th.
