Size of the spot metering.
The D800 manual on page 115 says that the spot metering takes place over a 4 mm diameter circle. I assume this is 4 mm on the viewer. It looks to me as though the little focusing retangle is about 1 mm wide, which makes the 4mm area seem fairly large. Am I thinking correctly?
