  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 Override 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

conventional­manner. 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 Manual Override, 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 completely 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.

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 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 ).

Single Shot

In Single Shot setting (AF S), the shutter release will be blocked until the camera finds the optimum focus setting. This ensures that no captures can be made that are not finely focused. However, this delay will normally be only a fraction of a second in good lighting conditions with a clear focusing pattern.
