a, b, c, and d Modes
Shooting in b Mode (Shutter-Priority Auto)
In shutter-priority auto mode, you choose the shutter speed while the camera
automatically selects the aperture that will produce the optimal exposure. Use slow
shutter speeds to suggest motion by blurring moving subjects, high shutter speeds to
“freeze” motion (A40).
1Rotate the mode dial to b.
2Rotate the command dial to choose the desired shutter

speed.

Shutter speed displayed in the viewfinder will change.
Set shutter speed to the desired value between 1/4,000s
and 30s.
Shutter speed can also be displayed in the Shooting
information display by pressing K (L).
3Frame a photograph, focus, and shoot.
DShutter Speed and Camera Shake
To reduce or prevent blur caused by camera shake, the shutter speed should be faster than the
inverse of lens focal length in seconds. For example, when using a lens with a focal length of
300mm, choose a shutter speed faster than 1/300s. A tripod is recommended when shooting at
slower shutter speeds. To reduce blur, try increasing shutter speed by increasing ISO sensitivity
(A53), using the built-in flash (A64) or an optional Speedlight (A150), or by mounting the
camera on a tripod, or using a vibration reduction (VR) lens (A20).
