■ Exposure Timing
The exposure timing setting selects the timing for the sensor exposure relative to the recording
synchronization signals.
With the HX, GX and fx cameras, there are differences in the sensor exposure timing relative to
the recording synchronization signals. If performing synchronized recording with the HX, GX
and fx cameras, the exposure timing for all of the cameras must match.
There are three types of exposure timing, as follows.
GX Native Exposure starts with the synchronization signal. Exposure timing for HX,
GX and Q cameras.
K4 Compatible Exposure ends with the synchronization signal. Exposure timing for fx-K4,
fx-K5.
The same exposure timing as the fx-K4, fx-K5 when recording
100/250/500pps.
K3 Compatible Exposure ends with the synchronization signal. Exposure timing for fx-K3,
fx RX-5/RX-5G.
The same exposure timing as the fx-K3 when recording 100/250/500pps.
GX Exposure Timing (exposure timing that can be selected with HX and GX cameras)
GX Native
K4 Compatible
K3 Compatible
fx Exposure Timing (exposure timing that can be selected with fx cameras)
K4 Compatible
K3 Compatible
Q Exposure Timing (exposure timing that can be selected with Q cameras)
GX Native
K4 Compatible
If recording at 1000pps with the fx camera, the “K4 Compatible” and “K3 Compatible” exposure
time is the same.
If the frame rate with the fx camera is 100/250/500pps, match the exposure timing with the “fx
Exposure Timing” settings.
If the frame rate and shutter settings match, the exposure time for the fx-K4, fx-K5 are “K3
Compatible” and 100/250/500pps recording can be the same as that for fx-K3, fx RX-5/RX-5G/
and fx
RX-6.
Also, with fx-K3, fx
RX-5/RX-5G, fx RX-6 versions are 2.30 or higher, “K4 Compatible” can be
selected.
If performing synchronous photography only with HX, GX and Q cameras, we recommend that GX
native be selected but if recording with HX, GX, Q and fx cameras, select the compatible mode if
coordinating the camera exposure timing.
If changing the shutter settings for each camera head with GX-5/GX-5F, the compatible mode must be
selected.
The “Exposure Timing” settings are disabled when the HX and GX-8 camera frame
straddling function is disabled.
