Exposure Control
Metering modes TTL max. aperture metering with a 21-zone silicon photocell.
1. Evaluative metering
(linkable to any point)
2. Partial metering
(approx. 8.5% of viewfinder at centre)
3. Centre spot metering
(approx. 2.4% of viewfinder at centre)
4. Spot metering
(linked to focusing point at approx. 2.4% of viewfinder)
*During continuous shooting with metering modes (3) and (4), the first shot is metered in real time and the meter reading is locked (AE lock) for subsequent shots in the same burst.
5. Multi-spot metering
(Max. 8 multi-spot metering entries)
6. Centre-weighted averaging metering
   
Exposure Control Methods
1. Program Ae (shiftable), 2. Shutter speed-priority AE (in 1/3, 1/2 or full stops, safety shift enabled with Custom Function), 3. Aperture-priority AE (in 1/3, 1/2 or full stops, safety shift enabled with Custom function), 4. Depth-of-field AE, 5. E-TTL program flash AE (high-speed sync, FE lock, and wireless control enabled with 550EX), 6. A-TTL program flash AE, 7. TTL program flash AE, 8. Manual, 9. Bulb.
Metering Range EV 0-20 (at 20° C/68°F with 50mm f/1.4 lens, ISO 100)
ISO film speed range ISO 6-6400 (Set automatically with DX-coded film at ISO 25-5000.)
Exposure Compensation
(1) Autoexposure bracketing (AEB): +/- 3 stops in 1/3 stop increments. Standard exposure, underexposure, and overexposure sequence. Repeated bracketing enabled according to current film advance mode. With self-timer, all three bracketed shots are taken in the continuous shooting mode regardless of the film advance mode.
(2) Manual exposure compensation:
+/- stops in 1/3-stop increments set with the Quick Control Dial or exposure compensation button and Main Dial.
(3) AEB and manual exposure compensation:
can be set together.
