What is Lens Memory and how is it used?
Most people use the Lens Memory feature as an alternative to using an external anamorphic lens for widescreen movies. As the name suggests, Lens Memory lets you set up the image size, position (by lens shift), and focus of the projector lens and then store those settings in memory so they can be recalled later. Setting up for widescreen is fairly straight forward. Naturally, this would require the use of a widescreen formatted screen (2.35:1 or 2:40:1 aspect ratio). All you need to do is adjust the projector lens to zoom, position (lens shift), and focus the widescreen formatted movie to fill your 2.35:1 screen, and then store that setting into memory. You can name this memory setting anything you want. Next, change your video to a 16:9 source and then readjust the lens zoom and shift (image position) so the image fills the screen from top to bottom and is centered horizontally (don’t readjust focus – see tips below). Store that setting into memory and name it. Now you can use the remote control, or discrete command codes, to recall your stored settings for 16:9 HD and widescreen 2.35:1 image sizes. You might also want to set up a third lens memory setting for widescreen movies that use closed captioning, which is sometimes located in the black bar at the bottom of the letterboxed image.
