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.
