Manual focus
There is both a Manual focus mode setting and a ManualOverride capability. Manual
focus is a specic setting that you actively make, whereas ManualOverride 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 conventional
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 autofocus, you must
make a new setting (by pressing the AF button and choosing AF S or AF C).
With ManualOverride, you can manually alter a focus setting that has been made in the
autofocus mode, 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 pressure on the shutter
release button and pressing again, the autofocus function is immediately reactivated.
Manual focus mode
The Manual focus mode is set by the front control wheel on the grip in the following
manner:
In camera active mode:
1) Press the AF button on the grip.
2) Turn the front control wheel to: Manual
3) Press Save to store the setting.
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 innity and closest distance marks on the
lens scale can appear to be positioned beyond the central index. This is only an apparent
eect and does not change the focusing range of the lens.
Autofocus override in Manual mode
See the following section for a description of how to use the advantages of a rapid auto-
focus check while remaining in Manual mode.
Autofocus
Autofocus mode can be either Single Shot, Continuous or True Focus (see note below)
and is activated by pressing the shutter release to the half-press position. Its operative
range from EV1 - 19 at ISO100. The point of focus is determined according to the verti-
cal and horizontal areas (see illus 4.) within the central rectangular zone on the focusing
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. Alternatively, a suitable
attached ash 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 ).
Single Shot
In Single Shot setting (AF S), the shutter release will be blocked until the camera nds
the optimum focus setting. This ensures that no captures can be made that are not nely
focused. However, this delay will normally be only a fraction of a second in good lighting
conditions with a clear focusing pattern.
