This section provides a description of the electronic shutter, together with setting and handling directions.
The table below lists the shutter modes in which the unit’s electronic shutter can be used as well as the shutter speeds which
can be selected.
For eliminating flicker due to lighting
For shooting fast moving subjects clearly
For shooting monitor screens in a way that minimizes the
pattern of horizontal lines
For shooting images when adding effects to the subjects’
movement
SYNCHRO SCAN:
Shutter is set using angle (deg) irrespective of
frame rate.
SYNCHRO SCAN2:
Shutter is set using time (sec) irrespective of
frame rate.
For shooting images when adding effects as if taken with
film
Notes
No matter in which mode the electronic shutter is used,
the higher the shutter speed, the lower the camera’s
sensitivity.
When the aperture is in the automatic mode, it will
increasingly open and the depth of focus will become
shallower as the shutter speed is increased.
By setting the shutter speed on the time axis (1/60, 1/100,
1/120, 1/250, 1/500, 1/1000, 1/2000), the frame rate can
be varied while keeping the exposure constant.
This is equivalent to Ramping (compensating for changes
in the frame rate using shutter angle) in a conventional film
camera.
*1 Not displayed in 720P mode. Corresponds to REC FORMAT option.
*2 The “F” of “1/F” is the frequency corresponding to the frame rate when using the VFR function. For example, when the VFR function is
used with a frame rate frequency is 15, the variable range of the SYNCHRO SCAN is at 1/15 or more.
