Evaluate and Adjust
View the image of your SpyderLENSCAL target on the camera screen or on your
computer. Zoom in on the ruler to evaluate the point of sharpest focus. Critical
evaluation is needed at this point. Some camera LCDs provide better playback than
others. Viewing the image in your preferred editing program should provide you with
the highest quality playback.
If the sharp focused mark is not "0", enter the autofocus correction menu on your
camera (this can be found in your camera's manual). Be sure you are adjusting by lens
and not making a global correct to any lens used with the camera. When the mark of
sharpest focus is above "0" your camera and lens are back focusing. You should adjust
forward to make a correction. When the mark of sharpest focus is below "0" your
camera and lens are front focusing. You should adjust backward to make a correction.
Note: The numbers on the SpyderLENSCAL ruler do not correlate to the numbers in the
adjustment menu in your camera.
Sharp Focus on 0 – No Adjustment Needed
