 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

conventional­manner. 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.

 AUTO / MANUAL FOCUS SETTING

1)Press AF.

2)Turn the FRONT scroll wheel to select Single Shot, Continuous, True Focus or Manual as required.

3)Press SAVE.

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

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.
