Projection distance for 16:10 aspect ratio screen
Unit: feet
Unit: meters
•
The value for L (distance to screen) varies slightly within ±5% depending on the zoom lens characteristics.
•
The zoom lens characteristics may cause slight image distortion.
•
When vertical keystone correction is used, the image is corrected in the direction that reduces its projected size.
•
The brightness varies depending on the zoom setting.
Note: When the fixed-focus lens ET-ELW21 is mounted, the optical lens shift function cannot be used.
