เอามาจาก Projectorcentral.com ครับ
The Z5 uses the same sleek gray casework as the Z4, complete with motorized lens cover. The cover opens automatically when you power the projector on, then closes up again when it's turned off. This will help to keep dust off of the lens without forcing you to remember to replace the lens cap or flip up the front cover as on the older Z3.
The connection panel is almost identical to that of the Z4, with one major addition: The PLV-Z5 has two HDMI ports to the Z4's one. This will allow the connection of two high-quality digital sources to your projector without requiring the use of an HDMI switching device. In addition, there are two YPbPr component inputs, S-Video, composite video, a VGA port, and a service port. The Z5 should have ample connection options for most any set of home theater equipment.
The PLV-Z5 retains the same extensive zoom and lens shift as the older Z4, allowing you to display a 100" diagonal image from 10.1 feet to 20.1 feet. As with the Z4, the lens shift in neutral position puts the center of the image at the same height as the centerline of the lens. From this position, the image can be shifted 150% above or below the lens, or 50% of the picture width to either side. This allows for a wide range of mounting options, including short throw from a coffee table, short or long throw from a ceiling mount, and long throw from a rear shelf mount. Note, however, that the extreme edges of horizontal and vertical shift cannot both be reached simultaneously, and using the extremities of the shift range can cause a drop in lumen output. The Z5 is one of the most flexible projectors available in terms of mounting options, and should fit most any theater without a hitch.
The PLV-Z5 likewise retains the Z4's dual-iris system. With an iris on the lamp and lens, the Z5's lumen output is highly variable. Closing both irises gives stellar contrast to dark-room home theater, while opening them allows for a moderate degree of ambient light in the room.
The auto-shutdown feature will turn off the Z5 automatically if a signal is not detected for five minutes. If you or your family members occasionally forget to turn off the projector after use, this feature can save you many hours of lamp life.
