Alright, so what Ive noticed is if I have the focus set manually to a shallow depth of field and film one thing without movement it looks fine. But as soon as I bump the camera or move it a tiny bit, it goes out of focus. So my understanding is a DOF adapter will allow me to move around filming in the same DOF? What would be a cheap reliable one? I know Letus can get pricey.

Understanding DOF Adapters?

A DOF adapter is an adapter that allows you to put 35mm lenses on your video camera that was not designed for that purpose.
It works with the lens mount on the front, allowing you to attach the lenses of your choosing. The light goes through the lens, and is projected onto the ground glass. The ground glass is simply a grainy piece of glass that can hold the image. Your camera then films the image that is on the ground glass. The depth of field comes from the image on the ground glass. The image from the lens has either a large circle of confusion on the ground glass or a small one, giving you either deep or shallow focus.
If you get shallow depth of field without the adapter, then you don't need one. When you say everything goes out of focus, is that only during movement (as in once the camera is still again, the image is in focus again) or does it stay out of focus after movement. It may be your shutter speed. Try a higher one like 1/120.

Could be a loose lens element. You might want to try bringing it to a Panasonic Service Center by you and have them look it over.

The way he describes it, it seems like any tiny movement of the camera changes the focus. Which is why I think it may be a lens element issue.

Let's hope its not.
If you change the distance from your camera to your subject, you are going to go out of focus.
That's why you have to work the focus on the lens as you move the camera.
Are you doing that?
This is whats happening or if I move away from what I want to focus on because I am zoomed and my hands might shake a bit.
