: Setting the ISO Speed for Still PhotosN

178

 

As H1 (equivalent to ISO 51200) and H2 (equivalent to ISO 102400) are 
expanded ISO speed settings, noise (dots of light, banding, etc.) and 
irregular colors will be more noticeable, and the resolution lower 
compared with the standard setting.

 

As L (equivalent to ISO 50) is an expanded ISO speed setting, the 
dynamic range will be somewhat narrower compared with the standard 
setting.

 

If [z3: Highlight tone priority] is set to [Enable] (p.206), L (equivalent 
to ISO 50), ISO 100/125/160, H1 (equivalent to ISO 51200), and H2 
(equivalent to ISO 102400) cannot be selected.

 

When shooting with a high ISO speed, high temperature, long exposure, 
or multiple exposure, image noise (rough grain, dots of light, banding, 
etc.) and irregular colors may become noticeable.

 

When shooting in conditions that produce an extreme amount of noise, 
such as a combination of high ISO speed, high temperature, and long 
exposure, images may not be recorded properly.

 

If you use a high ISO speed and flash to shoot a close subject, 
overexposure may result. 

Under [z2: ISO speed settings], you can use [Range for stills] to expand 
the settable ISO speed range from L (equivalent to ISO 50) to H1 
(equivalent to ISO 51200) and H2 (equivalent to ISO 102400) (p.180).
