Projection distances by the type of projection lenses (optional)
The available lenses have been designed with different projector-distance to screen-width ratios (“throw ratios”).
Select the appropriate lens model for your projection distance and screen size. Consult the following tables and
Panasonics’s online Lens Calculator.

Note
The projection distances listed here involve an error of 5 %.•
When using geometric adjustment, alter the compensation so that the screen size becomes smaller than the •
specified size.
