Flash modes and functions !
Explanation of the ZR-45’s flash modes and functions.
This section explains ZR-45 flash modes and functions in combination with CLS compatible cameras and
CPU lenses. Functions and LCD displays vary when other types of cameras are used.
E-TTL mode ! ! ! ! ! !
Information obtained by monitor pre-flashes and exposure control information is integrated by the camera
to automatically adjust flash output levels.
TTL is recommended for standard shooting situations.
To take pictures using ZR-45 set in E-TTL mode, see “Basic operation”.
Adjust the flash output level automatically for a well-balanced exposure of the main subject and
background.
The main subject is correctly exposed regardless of background brightness. This is
useful when you want to highlight the main subject.
Setting the E-TTL mode ! ! ! ! !
In E-TTL mode, immediately before the flash fires, the ZR-45 fires a series of imperceptible pre-flashes to
analyze the information of the subject.
ZR-45 flash shooting distance range
The flash shooting distance range is indicated by numbers and a bar chart on the LCD. Set the shooting
distance within this range. The range varies depending on ISO sensitivity, camera's image area setting,
illumination pattern, angle of coverage and aperture. For more information, see
“Specifications”.
Auto setting of ISO sensitivity, aperture and focal length
When using with a ETTL-compatible camera and a CPU lens, ZR-45's ISO sensitivity, aperture and focal
length are automatically set according to camera setting. For more information about the ISO sensitivity
range, see the camera’s user’s manual.
E-TTL mode ! ! ! ! ! !
When insufficient light for correct exposure is indicated
When the ZR-45 fires at full flash output level, ready-lights on the ZR-45 and in the camera’s viewfinder blink
for approx. three seconds after shooting. In this case, underexposure may occur. To compensate the
exposure, use a wider aperture or move closer to the subject and reshoot.
The underexposure value (-0.3 to -3.0 EV) is displayed on the ZR-45’s LCD panel for approx. three seconds
while the above ready-lights blink.
Pressing Function button 2 recalls display of underexposure value in TTL mode.
