5 Flash modes
Depending on the camera or flash unit type, various TTL
flash modes and the SLAVE flash mode are available.
The video light can be switched on for videos.
The flash mode is set by using the assigned TTL, SLAVE
or LED button.
5.1 TTL operating modes
The TTL flash modes offer a simple method of obtaining
very good flash shots. In TTL flash mode, the exposure is
measured by a sensor in the camera. It measures the
light reflected by the subject through the lens
(TTL = "Through The Lens"). Here the camera automati-
cally determines the flash performance required for a
correct exposure of the shot.
The advantage of the TTL flash mode is that all factors
influencing exposure (e.g. filters, change of aperture
and focal length changes with zoom lens, extensions for
close-ups, etc.) are automatically taken into account in
adjusting the flash light.
If the shot is exposed correctly, the STATUS LED
lights
up in red for approx. 3 seconds (see 4.2).
To define the range of the flash unit, see table
(page 160).
Setting procedure
• Switch on the flash unit with the ON/OFF button
.
• Press the TTL button
on the flash unit to set the TTL
mode of operation
.
• Set a suitable mode of operation on the camera,
e.g. P, S, A .
• Tap the shutter release to transfer data between the
flash unit and the camera.
5.1.1 E TTL- and E TTL II - flash mode (Canon)
E-TTL and E-TTL-II flash modes are digital flash modes.
5.1.2 i-TTL/i-TTL-BL flash mode (Nikon)
The i-TTL flash mode is supported by CLS-compatible
Nikon cameras.
The i-TTL-BL flash mode are only supported by
CLS-compatible cameras if lenses are used that
transmit distance data to the camera
(for example, "D-AF Nikkor lens").
When shooting this data is taken into consideration in
addition in adjusting the flash exposure.
Some cameras do not support the BL function in
combination with SPOT exposure metering! In these
cases, the normal i-TTL flash mode is set.
