NOTE
t When the ash strobe lights, the following phenomena may occur. These are due to the ash band compensation function and are not malfunctions.
- Moving subjects look as if they have been stopped for a moment.
- The resolution drops when the ash strobe lights.
- Horizontal lines appear in the video when the ash strobe lights.
Using the ash band compensation function
The ash band compensation function is activated when there are large changes in brightness at the bottom of the screen regardless of whether there
is ash strobe light. The ash band compensation function may be activated depending on the shooting environment such as where a bright window has
zoomed in and then out. So, we recommend use of this function in shooting environments where ash strobe lighting is anticipated.
Even if ash strobe lighting occurs, sufcient ash band compensation function effect may not be obtained in some shooting environments.
Flash band compensation function operation conditions
f The conditions the ash band compensation function can be used in are 59.94i, 59.94P, 50i, or 50P mode and when the electronic shutter, digital
zoom, and variable frame rate functions are not in operation.
f Even if the ash band compensation function is enabled, the ash band compensation function is forcibly disabled if the camera is changed to a mode
where the ash band compensation function cannot be used.
To use the function again, return to a mode where the function can be used, and press the USER button to turn on the ash band compensation
function.
The ash band compensation function is disabled once the power is turned off.
