Tighten the 3 allen head screws around
the thread ring once you are happy with
the alignment of the image on the LCD.

Zoom in until the edges of the Ground
Glass (GG) disappear and there are no
signs of vignetting (dark corners or sides).
This will be your outmost zoom level. From
your outmost zoom level you may zoom in
further to achieve a different Field of View
(FOV).
D.
Focusing The Camera Lens To The Ground Glass:
1.
Point the adapter (Without a Lens attached) toward a well illuminated
surface (white wall, sheet of paper) and by using your Camera's IRIS AD-
JUSMENT or DIAL until the Ground Glass
(GG) Grain Pattern appears. Then, use your
Camera's FOCUS ADJUSTMENT or DIAL to
focus on the grain until the pattern is dis-
tinct. You may also use the AUTO FOCUS
function of your camera to focus on the
Ground Glass (GG) Grain Pattern. Once the
Grain is in focus, switch your camera back
to MANUAL FOCUS. Your Ground Glass
(GG) is now in Focus.
2.
Once you get your camera focused on the
GG properly, lock this focus setting down
(depending on your camera, you may
need to use tape to lock the focus ring in
place). You may want to write this number
down for future reference.
3.
Note: For each Field Of View (FOV) chosen
you may need to set your Camera's Focus once more. It may be desirable
to keep a log of ZOOM and FOCUS settings for each camera being used.
E.
Attaching The Lens Mount And Lens:
1.
Using the Allen Wrench Tool included with
your package, loosen the three (3) screws
