Exposure Metering TTL exposure metering using RGB sensor with approximately 91K (91,000) 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 approximately 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; equivalent to center-weighted when other lenses are used. Range (ISO 100, f/1.4 • Matrix, center-weighted, or highlight-weighted lens, 20 °C/68 °F) metering: 0-20 EV • Spot metering: 2-20 EV Exposure meter coupling Combined CPU and AI Exposure mode Programmed auto with flexible program (e); shutter-priority auto (f ); aperture-priority auto (g); manual (h) Exposure compensation -5 - +5 EV in increments of 1/3, 1/2, or 1 EV Exposure bracketing 2-9 frames in steps of 1/3, 1/2, 2/3, or 1 EV; 2-5 frames in steps of 2 or 3 EV Flash bracketing 2-9 frames in steps of 1/3, 1/2, 2/3, or 1 EV; 2-5 frames in steps of 2 or 3 EV White balance bracketing 2-9 frames in steps of 1, 2, or 3 477
