exposure compensation parameters.
Because we received many requests to make
exposure compensation possible by changing
the ISO speed in M mode, this feature has been
included in firmware V2.0. Among the above

Minimum shutter speed at ISO Auto expanded

Firmware
Reduce camera shake and subject blur at high shutter speeds in Av and P modes
Minimum shutter speed at ISO Auto
expanded from 1/250 to 1/8000 sec.
Up to now, [Min. shutter spd.] was 1/ 250 sec.,
however this has been expanded to 1/8000 sec. In
Av and P modes, you can now shoot with reduced
subject blur and camera shake due to high shutter
speeds.

Another function added to ISO Auto is an
expanded shutter speed for [Min. shutter
speed]. The minimum shutter speed that was
previously 1/250 sec. is now expanded to a
maximum of 1/8000 sec. By setting a high
shutter speed above a certain value when in ISO
Auto you can capture quick-moving subjects
Select [Min. shutter spd.] And choose a minimum
shutter speed
When the maximum aperture value
(or the minimum aperture value) is
forcibly changed when switching to
a lens with a differing aperture value
while in M mode, the ISO speed or
shutter speed will automatically shift
so the exposure does not change.
For example, 1/2000 f/2.8 ISO 400
will automatically switch to 1/1000
f/4 ISO 400
with reduced blur and prevent camera shake.
Use this to reduce blurring when shooting in Av
and P modes.
