ISO Sensitivity Settings

[ISO sensitivity]

Select from values between ISO 100 and 51200. Extended settings of from about 0.3 to 1 EV below ISO 100 and 0.3 to 1 EV above ISO 51200 are also available. b offers an ISO AUTO option.

[Auto ISO sensitivity control]

Highlight [On] and press J to enable auto ISO sensitivity control. If [Off] is selected, [ISO sensitivity] will remain fixed at the value selected by the user. The following 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. 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].
