2.1 Conventional focus setting
Set the lowest magnification (8x) on the zoom scale (5)
using the zoom setting (4). Turn the focus setting (6)
till the calibration mark ∞ on the scale for the object
distance (7) is detected. Look through the eyepiece
(2) at a distant object (e.g. a church spire). Set the
sharpness of the image by further turning the focus
setting (6) to the right or left.
2.2 Near focus setting (< 0.5 m distance)
For observation distances of under a half meter (macro
setting or near focus) initially proceed as described in
Section 2.1. Subsequently, slowly extract the refocusing
(8) until you get a sharp image.
Note:
The visual field is only very small in the
i
close-focus range. Therefore, a pinpoint focusing is
required.
3. Zoom setting
After you have sharply set the image in the smallest
level of magnification, you can further increase the
magnification as much as you want. Turn the zoom set-
