Changing from Mode M to Mode S
If you select a shutter speed of or (long time exposure) in mode M and
then select mode S without changing the shutter speed, the shutter-speed display will
fl ash and the shutter can not be released. Rotate the main command dial to select a
different shutter speed before shooting.
Shutter Speed and Camera Shake
To prevent blurring caused by camera shake, the shutter speed should be faster than
the inverse of the focal length of the lens, in seconds (for example, if a lens has a fo-
cal length of 300 mm, shutter speed should be faster than
1 /
300
s). Use of a tripod is
rec om mend ed when shooting at slower shutter speeds. To prevent blur, try increasing
sensitivity (
46), using the built-in Speedlight ( 94), or attaching a VR lens.
