Spot
Camera meters circle 4 mm (0.16 in.)
in diameter (approximately 1.5% of
frame). Circle is centered on current
focus point, making it possible to
meter off-center subjects (if non-CPU
lens is used or if auto-area AF is in
effect (
0 92), camera will meter
center focus point). Ensures that
subject will be correctly exposed,
even when background is much
brighter or darker.
