EXPANDED OPERATION AND FUNCTION
3-4. Selecting the Zoom Output Curve
Zoom speed characteristic curve (zoom output curve) with
respect to the rotation angle of thumb ring is selectable
among three kinds. Use the zoom output curve selector
switch “Curve” for selecting a zoom output curve.
*
The combination of three kinds of curves that can be selected
can be changed on the display.
Refer to
[
Specifying the zoom
curve mode
]
in "5-7-4. Ctrl screen".
3-5. Talk Back (Microphone)
Operation
When the camera has a talk back function, the talk back
switch on the top of the zoom demand can be used.
When it is pushed to “ENG” side, it is locked and a cameraman can talk with an engineering
sta. So long as it is pushed to “PD” side, a cameraman can talk with a producer.
3-6. Return Operation
There are two RET switches (RET1, RET2) on the grip of the zoom demand.
While the RET switch is held down, on air picture/being recorded picture can be seen in the
viewnder through camera control system when multi cameras are connected to its system.
3-7. Extender Selector Switch
Operate the extender by switching the extender selector switch on the zoom demand.
“ON” side : Extender function is enabled
“OFF” side : Extender function is cancelled(1x)
3-8.
IS Operation
ON/OFF operation of IS function (Image Stabilizer) becomes possible when used with the
lens with IS function.
Lens IS function ON : LED next to the IS switch is lit (green)
Lens IS function OFF : LED next to the IS switch is o
* To activate IS function, press IS switch. For details, refer to the operation manual for the lens.
* Even when other functions are assigned to the IS switch, the LED next to the IS switch indicates the
ON or OFF status of the lens's IS function.
3-9.
MEMO Switch
This function is used for the setting when Framing preset, Speed preset or Shuttle-Shot are
assigned. To use this Memory (MEMO) function, Memo function has to be assigned to either
AUX1 switch, AUX2 switch,
RET1, RET2 or IS
switch.
3-10. Zoom Track Function
(
Tracking
)
The zoom control range (zoom track) can be restricted.
This function provides that the range can be virturally set at any position.
(Both the Tele and Wide ends are within a limited area.)
[How to store the memory position for zoom track]
1
.
Zoom to any desired zoom track position (Tele side or Wide side) to be memorized by
the thumb ring operation.
2
.
Move to “MEMO” side on the zoom track switch.
3
.
By above steps (1) and (2), the memory position on each of the Tele and Wide sides
is stored. Also, storing only on either side is possible.
To change the setting, perform step 1 to 2. (The position set last overwrites the setting
in the memory.)
* The memory position of the zoom track can be stored once on each of the Tele and Wide sides.
However, the zoom track memory cannot be stored more than one on each of the Tele and Wide
sides.
* The stored memory remains, even after the power is turned o.
* When a zoom track position has been set already, and of the zoom track position changes as a new
position that goes over from the restricted range of the telephoto end and the wide-angle end, turn
the zoom track switch o so that the new zoom track position can be set.
[ON / OFF for the Zoom Track Function]
The ON / OFF for the zoom track function indicates as follows:
ON : Virtual zoom control range
Press “ON” side on the zoom track switch.
OFF : Normal zoom control range
Press “OFF” side on the zoom track switch.
*
In case the present zoom position is outside of the restricted range when the zoom track function
turns on, the lens will automatically zoom to the end position of the restricted range.
4-2.
Speed Preset Function
This function allows you to call the preset zoom speed any time you zoom.
[Storing the Zoom Speed and Direction]
Operate
the thumb ring
to determine the zoom speed and direction (toward the telephoto
angle or the widest angle) which you want to store, and press the MEMO switch while
holding this position.
*The stored zoom speed is applied to the Framing Preset.
[Moving to the Zoom Speed Memory Position]
When the Sped switch is pressed, the zoom starts to move at the preset speed and to the
determined direction (toward the telephoto angle or the widest angle) stored in section 1 and
stops at the zoom end.
[Canceling the Movement to the Zoom Speed Memory Position]
Movement in Speed Preset can be canceled by any of the following operations.
• Press Sped switch again.
• Press Stl1, Stl2, Fr1P, Fr2P, Fr1F or Fr2F switch.
• Operate the thumb ring.
4-3.
Shuttle-Shot Function
This function allows you to switch between the current zoom position and the preset zoom
position at the maximum speed.
*The default setting of AUX2 switch at the shipment from the factory is Stl1 function.
*Shuttle-Shot can store up to two positions, Stl1 and Stl2. Only Stl1 is described in the following
explanation, but Stl2 is set in the same way.
[Setting the Shuttle Memory Position]
Zoom to the position that you want to store. Keeping this position, press the Shtl switch while
holding down the MEMO switch.
*The position you stored here is dierent from the one you set in Framing Preset. The stored position
set here is retained even after the power is turned o.
[Moving to the Shuttle Memory Position]
Holding down the Stl1 switch will zoom to the shuttle shot position at maximum speed and
then stop. This shuttle shot position is maintained while holding down the Stl1 switch.
Release the Stl1 switch to return to the position prior to moving.
*Even when the zoom track function is enabled, the zooming range is not restricted for the shuttle shot
*When the F-drop precedence zoom range control function is enabled, the zoom can not reach the
shuttle shot position if the shuttle shot position is outside of the zooming range under restriction by this
function.
The following functions can be assigned to either AUX1 switch, AUX2 switch, Ret1 switch,
Ret2 switch or IS switch. Refer to “5 Display operation” for the detailed assignment
procedures.
4-1.
Framing Preset Function
Framing presets are functions that can reproduce a predetermined angle of view and move-
ment speed (zoom speed) multiple times.
Movement speed to the framing position is selected by assigning the Fr1P/Fr2P、Fr1F/Fr2F
switch.
• Fr1P/Fr2P :For the preset speed setting(Preset Speed)
• Fr1F/Fr2F :For the maximum speed setting(Fast Speed)
*
The default setting of AUX1 switch at the shipment from the factory is Fr1F function.
[Setting the Framing Memory Position]
Zoom to the position that you want to store, while holding this zoom position, press the Fr1P
switch while holding down the MEMO switch.(The setting method is the same for Fr2P, Fr1F,
and Fr2F.)
*Framing memory positions can be stored in one location with Fr1P and Fr1F, and one location with Fr2P
and Fr2F respectively. Positions set after this point will have priority.
*The position you stored here is dierent from the one you set in Shuttle-shot. The stored position set
here is retained even after the power is turned o.
[Moving to the Framing Memory Position]
Once the Fr1P switch is pressed, the zoom starts to move toward the framing memory
position at the preset speed and stops at the framing memory position. When the zoom
reaches the framing memory position, it stops and stays there.
[Canceling the Movement to the Framing Memory Position]
During movement to the framing memory position, the movement can be canceled and/or
switched to other zoom operation by any of the following operations.
• Press Stl1, Stl2, or Sped switch.
• Press a framing preset switch (Fr1P, Fr2P, Fr1F or Fr2F) that is not being executed.
• Operate the
thumb ring.
