Compensating for Auto Exposure

Holding the AV button on the back of

The camera and turning the dial adjusts
exposure compensation. When the dial

lines up on the middle, the optimal

exposure has been reached.

You can see that this compensation has

changed the ISO to 800.  Great! But the 

shutter speed remains the same.

I am shooting at 1080 30p and the 

shutter speed is below twice the frame rate. 
The shutter speed should be 60 

(1/60

th

of a second).
