Read this rst! Always follow these precautions
WARNING:
Do not look at or place your skin into the light emitted from the lens while the
projector is being used.
Doing so can cause burns or loss of sight.
zStrong light is emitted from the projector’s lens. Do not look at or place your hands
directly into this light.
zTurn off the power when moving away from the projection lens or projector.
Do not project an image with the lens cover attached.
zDoing so can cause re.
CAUTION:
Before replacing the projection lens, be sure to turn off the power and
disconnect the power plug from the wall outlet.
zUnexpected projection of light may cause injury to eyes.
zReplacing the projection lens without removing the power plug may result in electric
shock.
Do not stand in front of the lens while the projector is being used.
Doing so can cause damage and burns to clothing.
zStrong light is emitted from the projector’s lens.
Do not place objects in front of the lens while the projector is being used.
Doing so can cause re, damage to the object, or malfunction of the lens and
projector.
zStrong light is emitted from the projector’s lens.
Do not open the desiccant bag. Do not eat the contents.
Inadvertently ingesting desiccant could be harmful.
zIf the desiccant gets into your eyes or mouth, immediately rinse with plenty of water
and seek medical attention.
zKeep desiccant out of the reach of children.

■Hazard distance (IEC 62471-5:2015)
The distance from the projection lens surface, at which the emission reaches the Accessible Emission Limit (AEL)
of risk group 2, is known as the hazard distance (HD) or safety distance. The area where the emission exceeds
the Accessible Emission Limit of risk group 2 is called the hazard zone (HZ).
Within the hazard zone, never look into the light projected from the projector. The eyes may be damaged by direct
irradiation even if you look at the light just for a moment. If you are outside the hazard zone, it is considered to be
safe in all circumstances except deliberately staring into the light projected from the projector.

■Risk group
The combination of the projector and the projection lens is categorized as risk group 2 when the hazard distance
is 1 m (39-3/8") or less. It is categorized as risk group 3 when the hazard distance exceeds 1 m (39-3/8"), and it
will be for professional use instead of consumer use.
In case of risk group 3, there is a possibility of damaging the eyes by direct irradiation when looking into the
projection light from inside the hazard zone even for a moment.
In the case of risk group 2, safe use without damaging the eyes is possible in all circumstances except
deliberately staring into the light projected from the projector.
The risk group for the combination of the projection lens and a compatible projector is as follows.
Projector model Risk group
PT-MZ880 / PT-MZ780 / PT-MZ680 Risk group 2

■Supported projectors
PT-MZ880 / PT-MZ780 / PT-MZ680
Note
zThis manual omits the alphabets at the end of projector model numbers.
zModels other than the above may also be supported. Refer to the operating instructions for
your projector or the Panasonic website (https://panasonic.net/cns/projector/).
zIf the main version of the firmware of the PT-MZ880 / PT-MZ780 / PT-MZ680 is less than 1.03,
this Projection lens cannot be used. Update the firmware to the latest version before use.
Check the update procedure by accessing the page containing the latest information on
the firmware at the Panasonic website (https://panasonic.net/cns/projector/pass/).

Before Use
6-ENGLISH
1) Operate the projector to align
the focus of the center of the
image.
2) Manually turn the peripheral
focus adjustment ring as
shown on the left, and align the
focus of the peripheral areas of
the image.

Attention
zThe projected images sizes indicated on the peripheral focus adjustment ring are
approximate guides.
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
zMake sure that the projector power supply is switched off before attaching or detaching the
projection lens.
zAfter removing the projection lens, store it safely away from vibration or impacts.
zDo not touch the electric contact points of the projection lens with your fingers. Dust and dirt
on the contacts may cause contact malfunctions, while static electricity may damage the unit.
zDo not turn the gear (ring) part of the projection lens barrel by hand. Doing so may damage
the motor.
zDo 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.
zThe lens is made of glass. The lens could be damaged if brought into contact with or
rubbed against hard objects. Handle the lens carefully.
zUse a clean, soft and dry cloth to wipe away dust and dirt from the projection lens.
Do not use fl uffy cloths containing oil, water or dust for cleaning. The lens is easily
damaged, so do not apply excessive pressure when wiping it.
Attaching the Lens / Detaching the Lens
For details on attaching or removing the projection lens, refer to the operating
instructions for the projector.
Focus Adjustment
The focus balance of the center of the projected image and that of the peripheral areas
differs depending on the size of the image.
This lens is equipped with a function for adjusting the peripheral focus balance.

Note
zThe 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
zTo prevent blocking of the intake and exhaust vents, maintain clearances from walls and objects
of at least 1 000 mm (3'3") for the exhaust vent and at least 500 mm (1'8") for the intake vent.
zAvoid setting up in places which are subject to sudden temperature changes, such as near
an air conditioner or lighting equipment (studio lamps, etc.).

Projection relationships (continued)
Perform the lens position shift within the adjustment range.
Perform lens shift adjustment within the ranges shown in the following illustrations.
The focus may change when the lens position is shifted out of the adjustment range.
This is because the movement of the lens is restricted to protect the optical parts.
The following illustrations depict lens shift ranges for floor installations of the projector.
