Diopter Adjustment
Rotate the diopter adjustment ring for adjustment
of diopter.
Adjust so that A or B on aperture or black circle
indicating measuring area looks clear when
observing object through finder.
Adjustment would be easy starting with 1º
aperture where object near aperture looks blur.
Make sure to adjust diopter before
measurement. Diopter should be adjusted for
the eyesight of the person who will be taking
measurement. If diopter is not adjusted before
focus measurement, correct measurement value
may not be expected. This is because the focus
is actually off even if you think it is correctly in
focus. In addition, if diopter is not correctly
adjusted, you may see the aperture moving
depending on viewing angle.
* You sometimes see small black dots or stripes
in internal finder. It gives no effect on
measuring performance.
