[TTL-LOCK MODE]

Instead of adjusting flash level with each shot, TTL flash control can be locked for consistent results across a series of photographs.

[LOCK WITH LAST FLASH]
Flash output is locked at the value metered for the most recent photo. An error message will be displayed if no previously metered value exists.
[LOCK WITH METERING FLASH]
The camera emits a series of pre-flashes and locks flash output at the metered value.

To use TTL lock, assign [TTL-LOCK] to a camera control and then use the control to enable or disable TTL lock.

Flash compensation can be adjusted while TTL lock is in effect.
