Sony intro'd a pair of new ultra-compact six
megapixel digital cameras today, the Cybershot DSC-W50 and the DSC-W30. Both are about the same (3x Carl Zeiss optical
zoom lens, new, supposedly more user-friendly UI, higher light-sensitivity settings), the main difference seems to be
that the DSC-W50 has a 2.5-inch LCD screen while the DSC-W30's screen is only 2-inches.
