With a built-in Fujinon wide angle 23x zoom lens, superior low-light performance, and excellent sensitivity (F11 at 2000 lux), the GY-HM650 has ideal optics for challenging shooting environments.
That might be about to change, though, as South Korea's state-owned Korea Electronics Technology Institute has announced a new image sensor chip that promises to take "vibrant photos" in extreme low-light conditions -- all the way down to 1 lux, which is the equivalent light output of a candle shining one meter away.
