• 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.
