Frequently Asked Questions
What is a semi-short throw lens, and which installations does it suit?
Semi-short throw lenses provide a middle ground between standard and ultra-short throw, ideal for meeting rooms, training centers, and mid-sized venues with moderate distance requirements.
How do throw ratios of 1.3 to 1.65 XGA / 1.32 to 1.68 WXGA / 1.25 to 1.6 WUXGA enable flexibility?
These ranges support zoom adjustment across multiple resolutions, allowing a single lens to accommodate different screen sizes and institutional projector standards.
What advantage do vertical and horizontal lens shift provide in compact installations?

Yes, modest zoom provides enough flexibility to accommodate minor variations in screen size and throw distance without the complexity of extreme zoom lenses.
Can the LS2ST4 support both permanent and semi-permanent deployments?
Yes, the semi-short throw range and quick-release design make it adaptable for institutions transitioning between fixed and flexible projection setups.
