Specifications

Here's how it works (for the technically inclined):
1. First it makes and compares two separate readings for the overall average light level and
the central spot area.
2. If they are both similar, the average reading is used.
3. If the center is 2—3 stops darker than the overall average, the exposure will be increased by 1-
2 stops above the average setting.
4. As the difference approaches 5 stops, the adjustment actually decreases in an effort to
preserve the visual effect.
5. If the metering systems, on the other hand, find the center (spot) brighter than the surroundings
(average area), the exposure will be decreased progressively, so that the background can go
black, while preserving detail in the center (e.g. spot lit) area
* The effect of this programmed ABLC system is most pronounced at bright light levels.
* At medium light levels, the amount of correction is reduced somewhat, while at very low light
levels there will be no correction at all.
25. RESET BUTTON
This button is used to reset the shutter speed, interval time, film advance mode or exposure
compensation back to a default value. First, lightly press the Shutter Release Button to update the LCD
with your currently entered information. Now you may reset one, or single values as follows:
1. Press the Reset Button (found under the Control Button Cover) to
return all of the following items to their default values: (Fig. 85)
- Shutter speed to AUTO from any manually set time, bulb, or a TV mode.
- Interval Timer to 10 seconds from any manually entered time (0 to 3600 sec.).
* This changes (to 10 sec.) will occur whether the INT Indicator is blinking or not, and from
any operating mode, i.e. Self-timer, Interval Timer, or Long Exposure (Bulb) Timer.
- Film advance mode to continuous - If presently set for single frame shooting.
- Exposure compensation to +/-0 from any manually entered value (O to +/-4 EV).
2. Press the Interval Timer Button (INT), then immediately press reset.
3. Press the Exposure Compensation Button (+ / - ), then immediately press reset.
