Before Use

This zoom lens is a projection lens equipped with an EEPROM*1 and stepping motor.
*1 EEPROM: Electrically erasable programmable read-only memory

Supported projectors
PT-RQ50K

Note

Some of the alphabet letters at the end of projector model numbers may be omitted in this manual.
Models other than the above may also be supported. Refer to the operating instructions for your projector or the website (https://panasonic.net/cns/projector/).

Supplied Accessories
Make sure that the following has been provided.

Preparation

Before replacing the projection lens
Return the projection lens to the home position before replacing or removing it. For details on how to return the lens to the home position, refer to the operating instructions of the projector.

Attention

Make sure that the projector power supply is switched off before attaching or detaching the projection lens.
After removing the projection lens, store it safely away from vibration or impacts.
Do not touch the electrical contacts of the projection lens with your fingers. Dust and dirt on the contacts may cause contact malfunctions, while static electricity may damage the unit.
Do not touch the surface of the lens with bare hands. Finger prints and dirt on the surface of the lens will be magnified by the lens and lower the quality of the projected image. Place the supplied lens cover on the zoom lens when the projector is not in use.
The lens is made of glass. The lens could be damaged if brought into contact with or rubbed against hard objects. Handle the lens carefully.
Use a clean, soft and dry cloth to wipe away dust and dirt from the projection lens.
Do not use fluffy cloths containing oil, water or dust for cleaning. The lens is easily damaged, so do not apply excessive pressure when wiping it.

Attaching and Detaching the Lens
For details on attaching and detaching the projection lens, refer to the operating instructions of the projector.

Peripheral focus adjustment function
When you change the size of the projected image, the focal balance between the center and peripheral areas of the screen may shift. This shift in balance tends to increase proportionally with smaller throw ratios. The ET-D3QW300 / ET-D3QS400 / ET-D3QT500 is equipped with a peripheral focus adjustment function to correct the shift in focal balance between the center and peripheral areas of the screen.

The illustrations in this procedure depict attachment of the ET-D3QW300 onto the PT-RQ50K.

The structure of the peripheral focus adjustment part differs depending on the projection lens type.

Adjusting the focus

Loosen the lock screw by turning it counterclockwise.
Turn the lens barrel tip or peripheral focus adjustment ring in the direction of the arrow to match the projection distance displayed on the lens to the actual distance from the lens to the screen.
Tighten the lock screw by turning it clockwise.
Operate the projector to align the focus of the center of the projected image.

Note

The projection distances displayed on the lens are approximate guides.

Lens calibration
Perform lens calibration after attaching the lens.

The illustrations in this procedure depict use of the ET-D3QW300 as an example.

Projection relationships

The dimensional relationship between the screen and the projector is shown below.

Dimensional relationship diagram

Note

This diagram assumes that the size and position of the projected image will be adjusted so that the image fills the entire screen.
This illustration is not drawn to scale.

Dimension for L1 (approximate values)

Note

The illustrations of projectors in this manual are for informational purposes only and do not represent a specific projector model. Configurations may vary with the model.

Attention

To prevent obstruction of the intake and exhaust vents, install the projector with a clearance at least 500 mm (1 ft. 7 in.) from walls and objects.
If you are installing the projector in a sealed space, be sure to provide additional air conditioning equipment and ventilation equipment. Insufficient ventilation will result in an accumulation of heat and may activate the projector’s protection circuit.
Avoid setting up in places which are subject to sudden temperature changes, such as near an air conditioner or lighting equipment (studio lamps, etc.).

Dimensional relationship
For details on the projection distance (L), refer to “Projected image size and Projection distance” and “Projection distance formulas” in the Appendix.

Lens shift ranges

After moving the lens to the home position according to “Lens calibration” on page 6, you can use the lens shift adjustment function on the projector to adjust the position of the projected image within the respective lens shift ranges based on the optical screen center position (standard projection position). The optical screen center position is the screen position using the optical center of the projector as the base. Perform lens shift adjustment within the ranges shown in the following illustrations. Moving the lens outside of the adjustment ranges may alter the focus. This occurs due to limitations in lens movement that are intended to protect the optical components. The following illustrations depict lens shift ranges for floor installations of the projector.

Note

The home position of the projector a point of origin position for the lens shift (i.e., vertical and horizontal positions of the lens) based on the results of lens calibration. It is not the optical center position of the screen.

Specifications

Check the specifications of each projection lens, and use the appropriate lens for your intended use.
