Important T eater Guidance

1. The projection screen should have a minimum 2.5-inch screen border and be in the 2.25:1 aspect ratio for multimedia content. A 2.4:1 screen may also be used for primarily 2.4:1 content with optical zoom adjustments or cropping for 16:9 content.
2. The projector lens center should be positioned between 4 inches below and 12 inches above the top edge of the screen surface, with an ideal position of about +3 to +5 inches. The projector lens should also be horizontally centered on the screen within +/- 3 inches.

ABOUT GEOMETRIC DISTORTION AND CHROMATIC ADJUSTMENTS.

Anamorphic horizontal expansion lenses create a slight “pincushion” shaped curvature especially at the edges of the image which decreases as the projection distance is increased for a given screen size. See the Image Geometry estimator in the Lens Selector at www.panamorph.com for the approximate distortion to expect. Masking the edges of the image by the screen border makes this distortion much less noticeable especially for dramatic content. These lenses may also reveal a slight splitting of white test pattern lines into red, green and blue components most visible at the far left and right sides. While this splitting may not be noticeable at normal viewing distances, any misconvergence can be reduced with the projector’s Panel Alignment feature.

CLEANING

Small amounts of dust and wipe marks are very noticeable on lens surfaces with a high brightness projection beam but typically will not impact the image as much as damage from excessive cleaning in pursuit of a “perfect” optical surface. Occasionally blowing off the lens surfaces with clean air is the best way to keep long term performance. If there is any excessive residue or build- up then it is recommended that you clean the optics with professional lens cleaning supplies such as from a camera store while the lens is in front of the lit beam of the projector. This will allow you to quickly see if the cleaning process is causing any damage. Note that the lens can be disassembled for cleaning by removing the front two screws and then carefully removing the components. However, any consequences of such disassembly is not covered by warranty or support.

Installation Steps

1. Install the Lens Retainer: Remove the two front assembly screws and remove the retainer. Adjust the projector lens shift to vertically and horizontally center the projector lens. Squeeze the retainer and work it into the projector opening to nest with the inside rim of the projector housing with prongs toward the ceiling and the top ridge aligned with the projector top-front rib. Tighten the three retainer screws just enough to prevent rotation.
2. Prepare the Projector: Adjust the projector roll, tilt, and/or yaw so that the projector test pattern lines are square to the screen edges. Adjust the zoom and vertical lens shift to center the test pattern on the screen. Change to a 2.4:1 movie instead of the test pattern. Set the Sony anamorphic lens menu setting to 1.32x for a 2.25:1 screen or 1.24x for a 2.4:1 screen. Set the Sony Aspect button on the remote to V-Stretch.
3. Install the STE Lens: After removing the rear STE lens cover, install the STE lens/mount assembly over the retainer prongs. Insert and tighten the two assembly screws to secure it (do not over tighten). Remove the front protective film.
4. Adjustments: Tilt the STE lens in its mount to make any residual image top curvature the same but opposite that at the bottom. Make final adjustments to projector zoom and vertical lens shift to achieve the best fit of the image to the screen. Lock the STE lens tilt by tightening the single Phillips tilt lock screw (do not over tighten). If desired, you may also adjust the panel alignment in the projector according to the Sony instruction manual.
5. Decide How to Watch Other Content: Use the Sony Aspect button to select “Squeeze” (anamorphic to 1.24x) to watch 16:9 content (including menus) in the screen center, or “Normal” to stretch 16:9 content to fill the entire screen width. On a 2.4:1 screen, zoom down the image to avoid cropping the top and bottom. Use V-Stretch with 1.24x for 2.0:1-2.2:1 content.
