5.5 Adjusting Zoom Levels
Î To adjust zoom levels:
1. Use the Zoom buttons
located above the Navigation pad on the back of the Onsight device.
x To adjust the zoom one step at a time, press and release the Minus (–) button (zoom out) or the Plus (+)
button (zoom in).
x 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 Onsight device is in Manual
Focus mode.
2. If you need to get very close to your subject, set the zoom level to 1x (minimum zoom) and move the Onsight
device until you reach the desired image size. This will ensure that you achieve the best focus.
5.6 Focusing
5.6.1 Automatic Focus
The Onsight device 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 paragraph 5.6.2, Manual Focus, on page 38.
Note that zo
om and focus controls are available regardless of whether the Viewfinder is currently displayed.
5.6.2 Manual Focus
Î To set the focus manually:
1. Use the Zoom buttons
in combination with the Manual Focus button.
2. Refer to the table below for an explanation of the various manual focus options:
