2.Flange Back Adjustment
Please adjust as the following steps:
Step Four : Set the object 0.33m away from the camera sensor plane,
and adjust it to the center of the whole image.
Step One : Rotate the focus ring until the image to its clearest. Take the
horizontal line in the middle of the calibration tool as the reference and
observe the position of the deviating scale pointer to get the number of
horizontal lines.
Step Two : According to the deviation value and the reference below,
add or subtract the corresponding shim to complete the flange back
adjustment.
Note: The direction of infinity indicates positive deviation value .
The direction of the closest focusing distance indicates negative
deviation value
.
If there are more than three horizontal lines, add or subtract the
corresponding value .
Example: I f the scale pointer points to 3 spaces in the direction of the closest
focusing distance, the deviation value is -3 .
If the scale pointer points to 4 spaces in the direction of infinity, the deviation
value is +4 . At this situation, the shim value of " +3 " needs to be added to the
shim value of " +1 " .
Set the object 0.33m away from the camera sensor
plane, and adjust it to the center of the whole image.
