Two focus modes, autofocus using the Auto-Servo AF (Single Servo AF and
Continuous Servo AF) and Manual focus, are available with this camera.
Autofocus
• With the focus mode selector set to AF, lightly
pressing the shutter release button automatically
focuses the camera on the subject at the focus
area (page 9/48) and causes
viewfinder.

Auto-Servo AF

Camera automatically chooses Single Servo AF or Continuous Servo AF operation
according to the subject status, i.e. stationary or moving.
• Single Servo AF
Automatically activated when shooting a stationary subject.
The shutter can be released when the focus indicator
Once focused on a subject, keeping the shutter release button lightly pressed locks
focus (Focus Lock, page 52). However, if the subject starts moving, Focus Lock is
deactivated, and the focus mode automatically switches to Continuous Servo AF.
• Continuous Servo AF
Continuous Servo AF is automatically activated when the subject is moving. The
shutter can be released when the focus indicator
focus is not locked and the camera continues to focus on the subject until shutter
release. With a moving subject, Focus Tracking (page 108) is activated and the camera
continuously focuses on the subject. Also, F55/F55D will continue to focus firmly on a
main subject with Lock-On™.
• When Sports Continuous mode is selected, Continuous Servo AF is
automatically activated and the camera continuously focuses on the subject.

Manual focus

• Set the focus mode selector to M. Look through the
viewfinder and rotate the lens focusing ring until the
image appears sharp on the clear matte field in the
viewfinder. The shutter can be released whether or
not the subject is in focus and regardless of the
focus indicator status.
• Use Manual focus in situations where autofocus
may not work as expected (page 27) or with lenses
which do not allow autofocus operation when
attached to the F55/F55D (page 88).
• When using a lens with the A-M select function, set
the switch/ring to M to focus manually. If M/A
(autofocus with manual priority) is available with
your lens, Manual focus is possible either with the
switch/ring set to M or M/A. See the instruction
manual of your lens for details.
Manual focus using Electronic Rangefinder
Set the focus mode selector to M. The focus can be confirmed with
the viewfinder. The Electronic Rangefinder works with most Nikkor lenses (including
AF Nikkors when operated manually) having a maximum aperture of f/5.6 or faster.
Lightly press the shutter release button and while the meter is on, rotate the lens
focusing ring until appears in the viewfinder. The shutter can be released anytime.
The Electronic Rangefinder can be activated with any of three focus brackets
selected as the focus area (page 9/49).
