Exposure Compensation with the TTL Flash Unit
If the exposure compensation is combined with the TTL flash unit, only the amount of
flash is adjusted. The brightness of the background and the amount of flash can be
adjusted simultaneously by setting
q
to the center of the bar graph.
Using External Metering Auto Flash
Two- or three-level auto flash modes are available with AF200T,
AF280T, and AF400T.
When using the two- or three-level auto flash modes (red and green, or red, green and
yellow settings), set the aperture value as shown in the table. In the Aperture-Priority AE
Mode or when the shutter speed is set in the range of 1/30 to 1/1000 of a second, the
flash sync speed of
1/30 of a second is set when the flash is fully charged.
Multi-Burst Flash with the Pentax Dedicated Flash
When discharging more than two Pentax dedicated flashes, make sure that they are of
the same type, the combination of Type A and B or Type C and D (refer to the overview
of Flash Function on page 62).
