This Sony camcorder has a low light rating of 4-lux. That's not particularly good; however, Sony is well-known for having gain circuits that are outstanding and produce very little noise. I have found this to be true. For the test, I shot some footage at night here in my little bedroom studio using nothing but a small Bescor 50-watt LED light attached to the shoe with the cam on a tripod about 6-feet away.
The footage was shot in 1080P at 24A with cinema tones. Here are a couple of stills. You can click on them to enlarge (like most of the photos in my blogs), but keep in mind that these are full-frame HD, so they're very large, but nice.
