Metering
TTL exposure metering using RGB sensor with
approximately 180K (180,000) pixels
Metering method
•
Matrix
: 3D color matrix metering III (type G, E, and D
lenses); color matrix metering III (other CPU lenses);
color matrix metering available with non-CPU lenses
if user provides lens data
•
Center-weighted
: Weight of 75% given to 12 mm circle
in center of frame. Diameter of circle can be changed
to 8, 15, or 20 mm, or weighting can be based on
average of entire frame (non-CPU lenses use 12-mm
circle)
•
Spot
: Meters 4 mm circle (about 1.5% of frame)
centered on selected focus point (on center focus
point when non-CPU lens is used)
•
Highlight-weighted
: Available with type G, E, and D
lenses
Range (ISO 100, f/1.4
lens, 20 °C/68 °F)
•
Matrix or center-weighted metering
: –3–+20 EV
•
Spot metering
: 2–20 EV
•
Highlight-weighted metering
: 0–20 EV
