Unless you can use some VERY LONG focal length lens, such as 600-800mm your metering mode (測光模式) is not useful because the moon will appear to be too small in your viewfinder, you won't be able to get an accurate reading from the moon. Your camera's metering system will only be tricked by all the surrounding black sky.

Also, although I did not mention what metering mode to use, I mentioned there is a common exposure setting to use as a starting point for photographing the moon:
光圈f/8，快門 1/125，ISO 100

NOTE: The suggested setting is only a start. You can try and experiment with different exposures because there are many factors affecting the amount of moon light your camera is able to capture. For example, moon phase, season, the amount of light in your surrounding area (the less the better, so try to find a darker area to take photos of the moon), and the amount of pollution in your surrounding air (dust particles can block the moon light).

This is because all lens manufacture will allow the len's focus ring to turn beyond the Infinity Focus mark to compensate for any thermal expansion or contraction the lens may be experiencing. Meaning, if your current environment is very cold, your lens may be slightly shorter than normal, meaning your focal point will be shifted giving you an unsharp image. But of course if you use single point focus "使用單點對焦" the camera will make sure you get the sharpest image possible disregarding this thermal problem.

I understand this is probably very beyond beginner's knowledge and sorry for making it sound very complicated, but just in case more people are wondering about this, here is the answer.
