Frequently Asked Questions - CJ12ex4.3B Series CANON

How do I mount the lens on the camera?

Ensure camera power is off. Remove the dust cap, align the locating pin with the camera mount groove, fit the lens, turn the bayonet mount ring to secure, and connect the power/iris control cable.

How do I adjust the back focus?

Set extender to 1x, iris fully open. Zoom to telephoto, focus on a distant object. Zoom to widest, loosen flange back lock screw, turn adjusting ring to refocus. Repeat until both ends are sharp, then tighten the screw.

How do I switch between servo and manual zoom?

Use the zoom operation change-over knob at the bottom of the drive unit. Turn to SERVO for motorized zoom (using rocker seesaw) or MANU for manual turning of the zoom ring/lever.

How do I use the macro function?

Set lens to widest angle. Press the macro button to unlock, then turn the macro ring clockwise (viewed from camera side) to focus on very close objects (M.O.D. 10 mm). Zooming after macro may shift focus.

How do I assign functions to the switches?

Press the DISPLAY switch to turn on the display. Use the control key to select the switch label (VTR, RET, AUX, etc.) and press Set. Then choose the desired function (e.g., Fr1P, Shtl, Sped) using left/right keys and confirm with Set.

How do I adjust the iris gain?

Pull up the rubber cap on the iris gain adjusting trimmer. Set iris mode to A (auto). Turn the trimmer with a small screwdriver until no iris hunting occurs. Close the cap after adjustment.

How do I use the shuttle-shot function?

First assign 'Shtl' function to a switch (e.g., VTR). To store a position: zoom to desired spot, press and hold MEMO then press Shtl switch. To use: press Shtl to go to stored position at max speed; release to return to previous position.

How do I set the zoom tracking (zoom range limit)?

Enable [Trk] to ON via display menu or by holding MEMO and Instant Auto-Iris switches for 3 seconds. Then zoom to desired telephoto or wide limit, press Instant Auto-Iris while holding MEMO to store that position.

What is the extender for and how to use it?

The built-in 2x extender doubles the focal length. Move the extender lever to 2x to engage. Note that aperture becomes smaller (e.g., 1:3.6) and light loss occurs; adjust iris accordingly.

How do I clean and maintain the lens?

Use a lens blower or soft brush for dust. For fingerprints, use a clean cotton cloth with commercial lens cleaner, wiping gently in a spiral. Avoid benzene or thinner. Store with caps attached to prevent dust and sunlight concentration.

5-1-6. Speed Preset

This function allows you to call the preset zoom speed any time you zoom. Assign the "Sped" function to the VTR, RET, or AUX switch of the drive unit, or AUX1 or AUX2 switch on the zoom demand. This manual describes the "Sped" function assigned to the VTR switch.

1. Storing the zoom speed and direction
   

Operate the zoom rocker seesaw 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".

2. How to operate the speed preset function

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.

3. How to cancel movement in Speed Preset

Movement in Speed Preset can be canceled by any of the following operations.

1) Press the "Sped" switch again.→ Zooming stops.
2) Performing zoom operation with the zoom rocker seasaw / "Shtl" switch / "Fr1P" switch / "Fr2P" switch / "Fr1F" switch / "Fr2F" switch.

5-1-7. Framing Preset

There are three framing preset types based on how the settings are combined.

[Zoom]

This enables a predetermined picture angle and movement speed (zoom speed) to be reproduced easily.

[Focus] "IASE S/IASE-C S" type only

This enables a predetermined focus to be reproduced easily.

[Z+F] "IASE S/IASE-C S" type only

This enables the movement speed (focus speed, zoom speed) to a predetermined focus and picture angle to be reproduced easily.

The framing preset setting is changed on the Preset screen on the information display. The "Frame1" setting is changed to "Zoom", "Focus", or "Z+F".

Up to two framing presets, Frame1 and Frame2, can be stored in the memory. Only Frame1 is described in the description given on the following pages. Frame1 is indicated as Fr1P".

How to set the zoom speed to the framing memory position

Movement speed to the framing position is selected by assigning the "Fr1P" or "Fr1F" switch.

"Fr1P"----For the preset speed setting (preset speed) (Assigned to the AUX switch at the factory.)

"Fr1F"----For the maximum speed setting (fast speed)

For details on how to assign the switches, refer to 5-6. SWITCH OPERATIONS.

5-1-8 Clutchless Zoom ('-C S"LENS only)

The "-C S" lens clutchless incorporates a clutchless zoom mechanism.

Owing to the clutchless zoom mechanism, you are no longer required to operate the clutch when switching between the servo zoom and manual zoom. This mechanism allows you to use a slow steady servo zoom technique in the MANUAL mode.

Set the zoom operation change-over knob to the SERVO position to activate the clutchless zoom mechanism.

NOTE

The lens may be damaged if manual zoom operation is performed during the servo zoom operation.

Zoom operation change-over knob	Clutchless zoom mechanism	Operation
SERVO ON		Setting used when both servo and manual operations are needed Without operating a clutch, you can switch between the servo zoom and manual zoom.
MANU. OFF Set to MANU. when using only the manual zoom.

1 When IASE S or IASE-C S type lens is used, set the focus operation change-over knob to MANU. position.

When using the IASE S or IASE-C S type lens, the camera can be damaged if excessive force is used to try to turn the focus ring when the knob is left in the SERVO position.

2 Turn the focus ring to bring the near or far object into focus.

5-2-2. Servo Focus Operation

1 When IASE S or IASE-C S type lens is used, set the focus operation change-over knob to SERVO position.

2 Mount the accessory such as focus demand. For the details, refer to the operation manual of accessories.

The lens with built-in extender has the built-in 2x extender.

Use the extender lever to switch between 1x and 2x.

When the extender is used, note that the light quantity may decrease by the zoom ratio depending on the iris correction setting.

5-4. IRIS OPERATION

The iris operation mode can be switched between auto and manual with the iris operation mode change-over switch.

5-4-1. Automatic Iris Operation

Slide the iris operation mode change-over switch to the "A" position. The iris operation is performed automatically by the instruction from the camera, to keep the video signal level constant.

5-4-2. Manual Iris Operation

Slide the iris operation mode change-over switch to the "M" position. The iris operation is performed by turning the iris ring on the lens body.

NOTE

The iris operation mode change-over switch must be set to the M position before performing manual iris operations. The lens may be damaged if manual iris operations are forcibly performed with the knob at the A position.

When the instant auto-iris switch is pressed during manual iris operation mode, the iris changes to automatic operation mode while the switch is held down.

This adjustment can be performed on the information display. Refer to the Information Display Manual.

In macro shooting, the object distance becomes shorter than the normal minimum object distance (M.O.D.). The minimum object distance by macro operation for this lens is 10mm at the widest angle.

To operate the macro, press the macro button to unlock the macro ring. While holding it down, turn the macro ring at the rear of the lens clockwise as viewed from the camera side to allow macro shooting.

1 Set the lens to the widest angle by manual or servo zoom operation.

2 Bring the object into focus by turning the macro ring.

Macro operation is also possible at any zoom position other than the widest angle, but the object distance increases.

Multi-point Focus Shooting

In macro shooting, when zooming to change the focal length, the focal point varies.

The multi-point focus shooting technique uses this characteristic. The focal point is shifted by the zoom operation. Follow the steps bellow :

1 Zoom in to a far object, and bring it into focus by normal focus operation.

2 Zoom out to a near object and bring into focus by macro operation.

3 Zoom in to the far object again while not touching the macro button set by above step 2, and bring into focus again by normal focus operation.

5-6. SWITCH OPERATIONS

Functions can be assigned to the five switches: the VTR, RET, AUX switches, or AUX1 and AUX2 switches on the information display. "VTR", "RET", "Shtl", and "Fr1P" functions are assigned respectively by default.

The following steps explain how to assign the functions to the switches in basic mode. For further details, refer to the Information Display Operation Manual.

1 Press the DISPLAY switch to turn on the display.
2 After using the control key to select the name of the switch key to which the function is to be allocated, press the Set key. The name of the switch and the default or the previous setting now blink on the display.
3 Press the left or right key until the function to be changed to appears on the display.
4 Press the Set key. This completes the setting.
