Cinemascope Anamorphic Lens Solution
Except for the high end of the home theater market, anamorphic lenses and Cinemascope ratio screens (2.35:1) are a tiny, but fast growing slice of the market. Mitsubishi's solution, in the HC7000 doesn't eliminate the need for an anamorphic lens, (like the Panasonic), but does cut the cost way down, by eliminating the need for a motorized sled. Those sleds are usually half or more of the total price.
With the HC7000, if you buy a 2.35:1 screen and an anamorphic lens, they have a special aspect ratio, that adjusts the image so that you can watch 16:9 content, or 4:3 content, without removing the anamorphic lens from the light path, thus, no motorized sled needed.
The advantage, compared to the Panasonic solution, is that when watching 2.35:1 movies, you are using all the pixels of the projector (1920x1080). With the Panasonic, it uses its zoom lens to get the width, and a matching aspect ratio, but it still is using only about 80% of the pixels for a 2.35:1 image, instead of the 100%. Technically, that means more brightness, and, inherently, a slightly sharper image.
