What is TTL?
TTL (Through-The-Lens) is the standard flash exposure control mode for Speedlites
480EG, 200E, 160E and Macro Ring Lite ML-3 when used with the DCS 500 Series
camera. Additionally, TTL is available with Speedlite 540EZ in all camera exposure
modes except for direct flash in Program mode, as shown in the following table. TTL is
identical to A-TTL in almost every way, except there is no preflash. When the camera is
set to Program mode, TTL flash sets an aperture based on a program line that responds to
the ambient light level.
The availability of A-TTL or TTL depends on the user’s choice of Speedlite, camera
exposure mode, and whether or not the Speedlite is set for direct flash as follows:
