What's the difference in high contrast lens system and contrast ratio specs?
Answer:
The lens system is just to maintain sharp focus from the center all the way to the corners. They don't specify a contrast ratio because LCD contrast ratios aren't all that great. Usually in the 1000 to 1 region. not bad, but plasmas can do better along with CRTs. Contrast ratio has to do with the difference attainable between brightest whites and darkest blacks.
