171 Inches and Growing
The anamorphic lens is fixed, so what happens if you want to watch an 16:9 program? The image then has to be compressed horizontally so that when the lens expands it horizontally it will be properly proportioned. You'll have gray bars on the side, but motorized screen matting can solve that problem easily enough. But by electronically shrinking the image in preparation for the anamorphic lens' stretching process, you are, in effect, not using the full 1920 pixels of horizontal resolution in the chip!
Is it just me, or does anyone else notice the irony in employing an anamorphic lens so that you can use all the pixel on a 2.35:1 movie but then enduring a significant loss of horizontal resolution whenever you sit down to watch HDTV?
