Item
(1) Adjustment of auto focus
The following adjustments are performed automatically by establishing the auto focus adjustment mode and writing the following
data at address "13FD" sequentially. The adjustment items are as shown in the table below. When an adjustment is completed
normally, data "FF" is written, which should be confirmed before proceeding to the next adjustment.
Address Data Adjustment item
13 F D 0012 Adjustment of wide end
0008 Adjustment of tele end focus ∞ position
0006 Adjustment of wide end focus ∞ position
000D Adjustment of zoom tracking
Note 1: During the adjustment of ∞ position, a subject should be shot actually. Make this adjustment while shooting a subject with
a clear-cut outline. In the case of the adjustment of tele end focus ∞ position in particular, if it is performed without shooting
a distant subject actually, the ∞ position will not be adjusted properly.
Adjustment of wide end focus ∞ position: 3 m or more
Adjustment of tele end focus ∞ position: 50 m or more
Note 2: In the case of the adjustment of ∞ position, the depth of field is important in insuring accuracy. If the depth of field is deep,
the ∞ position may be adjusted improperly the subject hardly falls out of focus. Make this adjustment with the depth of
field being shallow (the iris opened).
It is possible to open the iris using the high-speed shutter.
1. Establish the normal mode.
2. Call the V-V adjust sports mode in normal operation. (Refer to the instruction manual.)
3. Display "CAM ADJ" by using the remote control for servicing.
4. Establish the auto focus adjustment mode.
5. Perform the adjustment of ∞ position.
6. After the completion of the adjustment of ∞ position, set the V-V adjust back to the off position.
After exiting the auto focus adjustment mode (writing data " FF" at address "13FE"), establish the camera signal
system adjustment mode (writing data " 00" at address "0000").
Adjustment method
