Troubleshooting Guide
ISO 100 cannot be set. ISO speed expansion cannot be selected.
If [z3: Highlight tone priority] is set to [Enable], the settable ISO
speed range will be ISO 200 - ISO 16000. Even if you expand the
settable ISO speed range with [ISO speed range], you cannot select
the H1 (equivalent to ISO 25600) or H2 (equivalent to ISO 51200).
When [z3: Highlight tone priority] is set to [Disable], ISO 100/125/
160, H1, or H2 can be set (p.180).
Even if I set a decreased exposure compensation,
the image comes out bright.
Set [z2: Auto Lighting Optimizer] to [Disable]. When [Low],
[Standard], or [High] is set, even if you set a decreased exposure
compensation or flash exposure compensation, the image may come
out bright (p.175).
I cannot set the exposure compensation while both manual
exposure and Auto ISO are set.
See page 223 to set the exposure compensation.
Even if an exposure compensation is performed, it will not be applied
for flash photography.
Multi Shot Noise Reduction cannot be set.
If the image-recording quality is set to RAW or RAW+JPEG, [Multi
Shot Noise Reduction] cannot be set.
The Live View image or movie shooting image is
not displayed during multiple-exposure shooting.
If [On:ContShtng] is set, Live View display, image review after image
capture, or image playback is not possible during shooting (p.238).
