Exposure lock? HV30
 

I just got the HV30 and wondering how you lock the exposure? Seems silly to ask, but I cannot figure it out.

Thanks in advance.

Push the joystick in, navigate to exposure, move joystick up and click in again I believe). You can only do this in certain modes, so if you're shooting fully auto it won't work.
I believe its covered in the manual, BTW.

When you have set the exposure to what you want all you have to do is press in the joystick. Then the exposure will be locked.
