with NightShot, SuperNightShot, or NightShotPlus have a built-in infrared emitter. When in that zero-light capture mode, these camcorders generally record monochromatic (green/white - sometimes black/white) video. The same "video quality" issues will apply as with regular visible light video. Larger lens filter diameter and larger imaging chip size = more light (visible or otherwise) in to the camcorder for recording. This is not a "low light mode" which uses a very slow (1/30 second) shutter speed to allow more visible light in to hit the imaging chip.
New to these forums. I am currently in the process of looking for a solid camcorder that has Sony's Nightshot Plus. So far I've looked at a lot of different camcorders and one that stands out the most is the HDR-SR11. It looks like it takes solid video when in complete darkness. Any help would be great.
