My Panasonic PV-GS150 is having an autofocus problem. It will be focused on a target and then will go out of focus and then come back in to focus. It does this repeatably. It used to stay focused on the target without continuously trying to re-focus.

Simplest answer is that you may have accidentally flipped the focus switch (A/M) on the lens to M. This turns off autofocus for that lens (which you might need to do if autofocus just can't resolve the image). Try turning it back to A.

Another possibility is that you're using an autofocus target different from the one you're expecting. The problem would be apparent regardless of lens choice, by being in focus in a different part of the image. You can press the arrow keys (while holding shutter release down halfway) to change AF targets, or change a menu setting to simply choose the closest target.

The shooting modes have no effect on focusing ability.

The camera would likely detect other focus-related problems (like servo failure).

It is a regulation problem with the lens.

Make sure that you have turned on autofocus. Search for settings for autofocus/manual focus.

sounds as though the focus motor worm gear is binding up. I have ,at times been able to take this assebly off the zoom lens ,oil it and reinstall it. very very light amout of floil, a very thin oil. Also the zoom motors worm gear binding will cause this problem, sometimes one of these motor/worm gear assemblies will have to be replaced.

The focus ranges for the PV-SD4090 is 20 cm to infinity. The focus ranges for the PV-SD5000 is 30cm to infinity, and 6cm to 50cm in macro mode.

If the camera is having a difficult time auto-focusing, you can try the FOCUS LOCK feature. This feature allows you to focus on another subject roughly the same distance from you and then move the camera back to the intended subject and take the picture without losing focus. First, turn the camera on and locate the Autofocus Target Mark in the center of the LCD. The AF Target Mark resembles an open and close bracket [ ]. Position this AF Target Mark on a subject roughly the same distance away as the subject the camera is having trouble focusing on. Press the shutter button halfway enabling the lens to focus. While holding the shutter button halfway down, aim the camera at the original subject and press the shutter button all the way down.
