The REALiS SX80's 1.5x zoom lens suppresses the distortion of images to the maximum extent. Made possible by a lens design technology Canon has accumulated in the past, the new SX80 is able to project images more faithfully.
The lens also features a 10:0 lens offset, which maintains the lower edge of projected images. The lower edge of the projected image matches the optical axis of the lens. This permits projection of high-quality images without the deterioration in image quality caused by keystone correction.
You can easily change the screen size to accommodate various venues and/or applications. It is now easier to set up the projector perpendicular to the screen without having to tilt the projector, or use the keystone correction.
