this line (the lens axis). On a Dimage 7 the off-set is 29mm. The same value is true for Dimage
5 and other cameras in the 7 series.
After you determined the off-set, you can mount your camera to the off-axial adapter.
First fully tighten the bolt and then loosen it until slot of the bolt is perpendicular to the
rim of the adapter. Try to position the adapter so that its rim is perpendicular to the lens axis.
Try to find lines on the camera as references. Usually the front side and / or the rear side of the
camera is perpendicular to the lens axis. In this case, you place the adapter parallel to this side.
Then you slide the adapter until the center of the bolt has the desired amount of off-set, i.e.
29mm on a Dimage 7. You may need a ruler or any straight object to help you access the
accuracy of the positioning. Finally, you tighten the bolt fully. You may need a coin for this. At
this stage, you probably want to mark the position of the bolt to save your effort next time.
Use a marker or even a sharp object to scratch the paint if you want the mark to stay
forever.
After you mount the adapter to the camera, you can now mount the camera to the vertical
rotator arm, where you do the axial adjustment.
Note that the off-axial adapter can correct tripod mount from either side of the lens axis.
