Adjusting Flange Back

Flange back adjustment may be required to correct a focal distance error generated due to attachment thickness of the installed lens.
Normally you do not have to make any adjustment, however, you can adjust focus of the installed lens with auto iris, when it provides images out of focus
at the maximum telephoto position. To adjust the flange back, follow the steps below.
