Flashgun supports shutter speed limitation on X-Sync (maximum speed synchronize
to flash) on SLR / DSLR /Mirrorless Cameras in general. If it does not support
HSS function of the camera, faster shutter speed settings than the maximum synchronize
speed will block the flash gun. With faster shutter speeds than the maximum sync speed
some part(s) of the image area would be shaded by the moving shutter leaves within
the flash duration. As a result the image is only partially exposed by the flash light.”.
HSS allows flashgun works under high speed shutter (max 1/8000s).
MG80 Pro HSS On & Off switch
The flash emitting operation in HSS mode is different from the normal flash mode.
With the HSS function, users can get a faster shutter speed which will result in
a lower guide number. This is equivalent to a lower flash output. The flash of HSS
cannot be measured by an external light meter. When HSS is on,
the exposure compensation setting of TTL mode offers the same -2EV to +2EV of
basic mode. Using the power control of "M" Manual mode under HSS,
the MG80 Pro offers 1/32 to 1/1 power range only. If power is set from 1/256 to 1/64+0.3EV,
“M” manual power setting will automatically change to 1/32 in HSS mode.
