Q:

How do I enable picture-in-picture manual focus magnification on Panasonic G3?

When I first bought the camera, manual focusing would bring on an overlay of the focus area over the entire scene on the screen. It looks like the picture on the left here: http://shop.panasonic.com/images/Content/mf.jpg
I'm not sure what I did, but I no longer have this feature enabled, and I can't seem to find out how to enable it - anyone with any idea?

A:

By turning the thumb wheel to the left you will get the pic in pic feature back.  Turning it to the right will magnify it again in full frame.
