Viewfinder Screen Adjustments
The following adjustments are provided to improve the
visibility of the viewfinder screen.
Although these adjustment may make the viewfinder
image clearer, they have no effect on the output video
signal from the camera.
Adjusting the eyepiece focus
Depending on the eyesight of the camera operator —
whether longsighted or shortsighted — the optimal
position of the viewfinder image varies. Adjust the
eyepiece focus to get the clearest viewfinder image for
your eyesight. First focus the image with the lens,
then adjust the eyepiece focusing knob. The
adjustment range is from –3 to 0 diopters
1) (default
when shipped is 0 diopters).
Using an optional part allows you to modify the
adjustment range to –2 to +1 diopters or –0.5 to +3
diopters.
For details, consult your Sony dealer.
