As requested by a friend. This is a low light test done by changing the gain. Two tests was done - Carpark View (3x zoom) with the only lights are the one street lamp at the carpark and two garden lamps at the walking lane for the shooting view; and the second half of this video is a Candle Light test

Settings:
Manual Adjust of White Balance unless iA or Auto is used
1/25 Speed

Gain or Iris is changed:
1. From 18db to 0db - Bright but quite a bit of noise at 18db n 15db. 12db n 9db are better. 3db - camera loses focus sometimes. Noise is expected from Consumer Camera. But we can see the details n color is quite accurate. I believe zooming also reduces the light coming into the camera n thus increases the noise level.
2. Other Low Light Modes, like Color Night View n Candlelight Scene Mode. The Color Night View really brightens up the whole scene but smooths out the image. I guess it really slows down the camera speed.

One Candle Light Test, I also added a few more test at the end after the Candle Light Gain Test:
1. Using AF/AE to set exposure. It works quite well.
2. Zoom to 12x test - when it reaches 10x, the camera finds it hard to zoom clearly in the dark. (Update Correction on 20 June - The problem is not so much zooming in the dark but the object was too close to zoom 12x so the camera loses focus at 12x. I tested it in a bright room)
3. One Lux Test (or approximately). According to the definition of 1 lux - it is the capture of images 3 feet away from 1 candle light. Using the Color Night View, the camera can really captures 1 lux brightly.

Overall the camera performs well in consumer cameras of this range.
