AF2:
AF Illuminator
Improves focusing in low light dark conditions by using a red light to aid
focusing. If the red light is annoying or intrusive, turn if off here. More related
to photography once more, but just in case it's good to turn this off.
AF track sens:
This has 5 settings, and it adjusts how much interference it takes the AF to
change to a new focus point, if something moves in front of the camera. This
is mainly for the photography side of things. As there is also a setting in
camera 2 menu for a similar thing.

Metering Mode:
Multi:
This divides the screen into multiple areas and measures the whole screen
area and adjusts accordingly for the average. If there are lots of bright parts
to your image it may underexpose or lots of darks it may overexpose. You can
use the exposure compensation dial on top of the camera to bring the
exposure back to where you want it to be.
Centre:
Measures the whole area, but emphasises the central area.
Spot: Large of Standard size
Measures the spot area and exposes for that part of the image. Good for high contrast
images such as a subject that is well lit, surrounded by a dark background.
Entire Screen Avg:
Averages the entire screen.
Highlight:
Takes the exposure off the brightest parts of your image and makes sure they are correctly
exposed.
Tip: When in Spot metering mode; Set Focus Area to 'Flexible Spot' or 'Expand Flexible
Spot', and then set the 'Spot Metering Point'; (in the 'Exposure 2' menu) to 'Focus Point
Link'. The spot metering is then taken from the focus area. So, where ever you place the
focus area on screen, the exposure will adjust according to the position it is in.
