uMonitor Preflashes

The SB-800 fires a series of imperceptible Monitor Preflashes just before the flash fires to obtain information on the subject in these cases:

(1)when the SB-800 is used with cameras compatible with CLS, digital SLRs not compatible with CLS, and cameras in Group I with a CPU lens, and the flash mode is set to TTL auto flash, and

(2)when the SB-800 is used with cameras compatible with CLS with a CPU lens, and the flash mode is set to Auto Aperture flash.

Monitor Preflashes are fired instantaneously and cannot be differentiated from the main flash, but H appears on the LCD panel (using a single flash unit). However, for cameras in Group I, Monitor Preflashes are not fired when the SB-800’s flash head is adjusted to other than the horizontal/front or down to –7° position, or the camera’s flash sync mode is set to Rear-curtain sync, even when H appears on the LCD panel.
