Turning the Illumination Ring On or Off
The light on the front of the MCD can be used to provide extra
lighting in dim lighting situations. There are two light settings
that trigger a different set of lights on the illumination ring. Use
the right cursor pad button to toggle the light settings:
Normal – optimized for distant objects
Macro – optimized for close-ups
Off – turns the light off
Note that if the MCD is displaying a configuration or directory screen, the
Light
button operates as a right arrow key. In this case, press and hold
the
Function
control button, then press the right cursor to adjust the light
setting.

Adjusting Zoom Levels
To adjust zoom levels, use the zoom buttons located above
the Navigation pad on the back of the MCD.
•
To adjust the zoom one step at a time, press and release the
Minus
(–
) button (zoom out) or the
Plus
(+) button (zoom in).
•
To adjust zoom levels at a faster rate, press and hold the
Minus
or
Plus
button, and release it when the zoom level is where you need it.
The minimum focusing distance changes with the zoom level. As you zoom
in, the minimum focus distance moves out. For example, if you are close
to an object and zoom in on it, the object will become out of focus if you
zoom in too far. The focus adjusts automatically when zooming unless the
MCD is in Manual Focus mode. See
Focusing
, next.
If you need to get very close to your subject, set the zoom level to 1x
(minimum zoom) and move the MCD until you reach the desired image
size. This will ensure that you achieve the best focus.

Automatic Focus
The MCD normally operates in automatic focus mode and will focus on
subjects centered in the viewfinder. Focus will continuously update as the
distance between the subject and the lens changes or as zoom is adjusted.
There are situations where manual control is desired to fine tune the focus,
particularly for objects not centered in the viewfinder. Manual focus control
is described in the following section.
Note that zoom and focus controls are available regardless of whether the
Viewfinder is currently displayed.
