  MANUAL FOCUS
There is both a Manual focus mode setting and a manual override capability.
Manual focus is a specific setting that you actively make, whereas manual over-
ride is always available as a temporary override of an autofocus setting.
In Manual focus mode, focusing is carried out by rotating the focusing ring in the
conventional manner. The focus setting remains until changed as with a conven-
tional non-autofocus lens. This means that pressing the shutter release button will
not activate a focus setting change as it does in autofocus. To change back to au-
tofocus, you must make a new setting (by pressing the AF button and choosing
AF S or AF C).
With manual override in autofocus mode you can manually alter a focus setting
that has been made, by rotating the lens barrel in the conventional manner and
without having to change modes. As long as the shutter release button is kept at
the half-press position, the new focus setting is maintained. By releasing the pres-
sure on the shutter release button and pressing again, the autofocus function is
immediately reactivated.
  AUTOFOCUS
Autofocus mode can be either Single Shot or Continuous and is activated
by pressing the shutter release to the half-press position. Its operative range is
from EV1–19 at ISO100. The point of focus is determined according to the vertical
and horizontal areas (see illus) within the central rectangular zone on the focus-
ing screen. When light levels are too low or the contrast of the subject is too low,
auxiliary illumination (situated on the top of the grip) is automatically activated if
desired. The operative distance is approximately six metres from the camera. Al-
ternatively, a suitable attached flash unit that has a similar facility (a Metz 54/70, for
example) can also be used instead. This feature can be altered in settings (Custom
options #16/AF assist light).
True Focus is also classified as an autofocus function and is normally activated by
its own button on the grip. See later section.

  MANUAL OVERRIDE IN AUTOFOCUS

MODE

Manual override is always possible in automatic focus mode
without any need to make a new setting; just rotate the fo-
cusing ring in the conventional manner. As the lens barrel
does not rotate in autofocus mode, you can hold the focus-
ing ring for instant manual adjustments as you would with a
conventional lens. However, to retain the new manual focus
adjustments, you must maintain the pressure on the shut-
ter release button. You can instantly return to the automatic
focusing mode by releasing the pressure on the shutter re-
lease button first and then pressing the release button half-
way again.
The instant manual override function produces a convenient
way of working. You can take advantage of autofocus while
retaining an instantly adjustable manual focus check if pre-
ferred for pin-point accuracy without making any changes
in the settings.
  AUTOFOCUS OVERRIDE IN MANUAL

MODE

See the following section for a description of how to use the
advantages of a rapid autofocus check while remaining in
Manual mode.

Natural friction is inherent in the design to purposely reproduce the secure feel of a
com pletely manual lens.
Please note that when focusing manually, the infinity and closest distance marks
on the lens scale can appear to be positioned beyond the central index. This is only
an apparent effect and does not change the focusing range of the lens.
