Lens shift system
This product has a lens shift system that can move the image position vertically and horizontally.
It is electrically driven through buttons on the projector or remote.
The lens shift range is as follows:
●
Lens shift mode: Normal
Projection lens
Direction
Amount of lens shift
Lens shift ratio
Ultra Long Zoom
Long Zoom
Standard Zoom
Wide Zoom
Vertical
Horizontal
55% / -15%
10% / -10%
10.5:-0.5 / 3.5:6.5
4:6 / 6:4
Short Fixed
Vertical
Horizontal
11.3% / -11.3%
4.6% / -4.6%
6.13:3.87 / 3.87:6.13
4.54:5.46 / 5.46:4.54
Ultra Wide
Vertical
Horizontal
75% / -15%
30% / -30%
1.25:-2.5 / 3.5:6.5
8:2 / 2:8
Moving to the maximum positions in both vertical and horizontal directions will cause the guaranteed
optical performance range to be exceeded.
This product is a system that only allows the lens to be shifted within the guaranteed optical performance
range.
The range of movement (guaranteed optical performance range) is illustrated later in a figure.
●
Lens shift mode: Expanded

With this setting, the lens can be shifted to the maximum positions vertically and horizontally, ignoring the
guaranteed optical performance range.
** Amount of lens shift is an approximate calculated value.
