MIN. SHUTTER SPEED ⁄–¼ SEC, AUTO AUTO

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 au-
tomatically 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 50mm, the camera will choose a minimum
shutter speed in the neighborhood of ⁄ s). The minimum shutter
speed is not a ected by the option selected for image stabilization.
