Lens shifting range
This projector is equipped with a lens shift function for adjusting the position of the projected image by using the LENS
SHIFT buttons (
→ page 30 ). The lens can be shifted within the range shown below.
NOTE:
• Please do not use the lens shift function when projecting portrait images. Please use it with the lens in the center.
Legend: V “Vertical” refers to the screen height and H “Horizontal” refers to the screen width. The lens shift range is
expressed as a ratio of height and width, respectively.

(Example calculation) If projecting on a 300 inch screen using an L4K-15ZM lens unit
According to the “Table of screen sizes and dimensions” (
→ page 149 ), H = 265.4"/674.0 cm, V = 139.9"/355.4 cm.
Adjustment range in the vertical direction: the projected image can be moved upwards 0.5 × 139.9"/355.4 cm ≈
70"/178 cm, downwards approximately 70"/178 cm (when the lens is at the center position). Adjustment range in the
horizontal direction: the projected image can be moved to the left 0.17 × 265.4"/674.0 cm
≈ 45"/115 cm, to the right
approximately 45"/115 cm.
* Figures differ by several % because the calculation is approximate.
