Choose the base sensitivity, maximum sensitivity, and minimum shutter speed for auto ISO sensitivity control, which is selected by rotating the ISO dial to [A]. Settings for [AUTO1], [AUTO2], and [AUTO3] can be adjusted separately.
Item | Options | Default | ||
---|---|---|---|---|
[AUTO1] | [AUTO2] | [AUTO3] | ||
[DEFAULT SENSITIVITY] | 12800–200 | 200 | 200 | 200 |
[MAX. SENSITIVITY] | 12800–400 | 800 | 1600 | 3200 |
[MIN. SHUTTER SPEED] | 1⁄500–1/4 s, AUTO | 1/60 s | 1/60 s | 1/60 s |
The camera automatically chooses a sensitivity between the default and maximum values. Sensitivity is only raised above the default value if the shutter speed required for optimal exposure would be slower than the value selected for [MIN. SHUTTER SPEED].
If the value selected for [DEFAULT SENSITIVITY] is higher than that selected for [MAX. SENSITIVITY], [DEFAULT SENSITIVITY] will be set to the value selected for [MAX. SENSITIVITY].
The camera may select shutter speeds slower than [MIN. SHUTTER SPEED] if pictures would still be underexposed at the value selected for [MAX. SENSITIVITY]. If [AUTO] is selected for [MIN. SHUTTER SPEED], the camera will automatically choose a minimum shutter speed approximately equal to the inverse of the lens’ focal length, in seconds (for example, if the lens has a focal length of 50 mm, the camera will choose a minimum shutter speed in the neighborhood of 1⁄50 s). The minimum shutter speed is not affected by the option selected for image stabilization.
