Fit the adapter into the ring and look at the LCD screen. 2.
Align the adapter until you have all edges of the Ground Glass (GG) 3.
parallel with the edges of the LCD screen (you may want to zoom in
until the edges of the GG are close to the edges of the LCD screen for
better alignment).
Tighten the 3 allen head screws around 4.
the thread ring once you are happy with
the alignment of the image on the LCD.
Zoom in until the edges of the Ground 5.
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).
Focusing The Camera Lens To The Ground Glass: D.
Point the adapter (Without a Lens at- 1.
tached) toward a well illuminated surface
(white wall, sheet of paper) and by using
your Camera’s IRIS ADJUSMENT 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 distinct. 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 FO-
CUS. Your Ground Glass (GG) is now in Fo-
cus.
Once you get your camera focused on the 2.
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.
Note: For each Field Of View (FOV) chosen you may need to set 3.
your Camera’s Focus once more. It may be desirable to keep a
log of ZOOM and FOCUS settings for each camera being used.
