Troubleshooting ISO 100 cannot be set. ISO speed expansion cannot be selected. zz Check the [ISO speed range] setting under [z: zISO speed settings]. zz When [z: Highlight tone priority] is set to [Enable] or [Enhanced], the available ISO speed range is ISO 200-40000 for still photo shooting. Even if you set [ISO speed range] under [z: ISO speed settings] to expand the setting range, you cannot select L (equivalent to ISO 50), H1 (equivalent to ISO 51200), or H2 (equivalent to ISO 102400). When [z: Highlight tone priority] is set to [Disable] (=137), you can set ISO 100/125/160, L, or H1/H2. Even if I set a decreased exposure compensation, the image comes out bright. zz Set [z: Auto Lighting Optimizer] to [Disable] (=136). 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. I cannot set the exposure compensation when both manual exposure and ISO Auto are set. zz See =103 to set the exposure compensation. Not all the lens aberration correction options are displayed. zz Although [Chromatic aberr corr] and [Diffraction correction] are not displayed when [Digital Lens Optimizer] is set to [Enable], both functions are applied in shooting, as when set to [Enable]. zz During movie recording, [Digital Lens Optimizer] or [Diffraction correction] will not be displayed. 568
