ISO Sensitivity Settings

[ISO sensitivity]

Choose from settings of ISO 64 to 25600; the camera also supports settings below ISO 64 by about 0.3, 0.7, and 1 EV (ISO 32 equivalent) and above ISO 25600 by about 0.3, 0.7, 1, and 2 EV (ISO 102400 equivalent).

[Auto ISO sensitivity control]

Select [ON] to enable auto ISO sensitivity control. If [OFF] is selected, [ISO sensitivity] will remain fixed at the value selected by the user. [Maximum sensitivity], [Maximum sensitivity with c], and [Minimum shutter speed] options are available when [ON] is selected.

[Maximum sensitivity]

Choose an upper limit for ISO sensitivity to prevent it being raised too high.

[Maximum sensitivity with c]

Choose the upper ISO sensitivity limit for photos taken using an optional flash unit.

[Minimum shutter speed]

Choose the shutter speed below which auto ISO sensitivity control will kick in to prevent underexposure in modes P and A; options range from ¹/_16,000 to 30 s. If [Auto] is selected, the camera will choose the minimum shutter speed based on lens focal length. For example, the camera will automatically choose faster minimum shutter speeds to prevent blur caused by camera shake when a long lens is attached.

• To view auto shutter-speed selection options, highlight [Auto] and press 2. Auto shutter-speed selection can be fine-tuned by choosing faster or slower minimums. Faster settings can be used to reduce blur when photographing fast-moving subjects.

• Shutter speeds may drop below the selected minimum if optimal exposure cannot be achieved at the ISO sensitivity chosen for [Maximum sensitivity].
