Figure 6. AC-371 rear base tilt unit.
Now the AC-371 rear base tilt kit is assembled you have added a 21,5mm
spacer [8] to the front standard to keep the optical axis of the lens board
aligned to the centre of the sensor. The rear base tilt unit [7] allows the rear
standard to tilt to a maximum of +/- 15º with fixed increments of 5º.
Note that you should always support the rear standard when you unlock the
base tilt unit.
The installed rear base tilt unit also allows for an extra 42mm of telescopic
travel [12]. If you will use this extra travel to its maximum extend, for the Actus-
B, the standard AC-210 bellow should be replaced by the AC-214 long bellow.
For the Actus-DB or Actus-G with DB module the ACDB-250 bellow should be
replaced by the ACDB-254 long bellow
