•Open the "Focus" dialog via "View > Focus zone" or click on in the toolbar.

Fig. 158: Focus zone

Autofocus

1.Enable the "Autofocus" option. In the live image the focus zone is displayed. Using the focus zone you define the image area on which the camera should be focused. The focus zone is divided into 25 fields. For each field you can set the field weight separately.

2.Set the top left corner of the focus zone via the "Offset X" and "Offset Y" input fields. Alternatively you can move the focus zone in the live image using the mouse.

3.Set the width and height of the focus zone via the "Width" and "Height" input fields. Alternatively you can scale the focus zone in the live image using the mouse.

4.Select a focus field in the live image by clicking with the mouse. If you want to edit multiple fields press the CTRL key while selecting.

5.Set the weight for the field in the dialog (Off, Weak, Middle, Strong).

6.Click on the "Apply settings" button to save the changed settings.

Note: If you operate the XS with low pixel clock and low frame rate, the focus responds more slowly. This effect is also visible when you edit the focus zone.

Manual focus

1.Disable the the "Autofocus" option.

2.Set the focus manually via the "Manual focus" slider.

3.Via the "Once" button you can adjust the manual focus singularly.

According to the sensor manufacturer, there is no guarantee that a focal point set manually will lead to a reproducible focal distance. A focal value determined with one model will not necessarily result in the same focal point for a different model.

Resetting the parameters

Click on the "Default" button to reset all parameters to the model-specific defaults.
