It sounds like the focus element in your lens is not functioning properly. Does the lens retract completely when you turn off the camera? When you push the button does the camera attempt to focus the image? If you do not see any change in the image when you push the button, and do not hear any sound - then your focus motor is either jammed or malfunctioning. David Millier Advance Camera Repair

I would check to see if your camcorder is set for autofocus or manual. If it got changed to manual by accident, that would explain it (you can USE manual, but you'll have to keep adjusting focus). If this isn't the problem I would take it to the dealer you got if from or a repair station.

With the camera you have, noise isn't much of an issue when pushing the ISO to 400, 800 or even 1600. Try setting at ISO 400 and change it to manual mode or shutter priority and then choose a faster shutter speed. Take some test shots. If it's still blurred, increase the shutter speed and ISO to 800 and try again.

The shooting modes are as follows: PROGRAM (P)/AUTO Modes. Used for general photography. The camera automatically makes the settings for natural color balance. In PROGRAM AUTO (P) the brightness (exposure compensation) can be adjusted. Portrait. Suitable for taking a portrait-style photo of a person. The camera automatically sets the optimal shooting settings to produce natural skin tones. Landscape + Portrait. Suitable for taking photos of both your subject and the landscape. This setting allows both the foreground subject and background landscape to be in focus. Landscape. Suitable for taking photos of landscapes and other outdoor scenes. The camera automatically sets the optimal shooting settings to produce vivid blues and greens. Night and Portrait. Suitable for taking photos of your subject in the evening or at night. Since the shutter speed is slow, it is advised that you use a tripod to support the camera in this mode to help avoid blur from camera shake. Night Scene. Suitable for shooting pictures in the evening or at night. The camera sets a slower shutter speed than is used in normal shooting. If you take a picture of a street at night in any other mode, the lack of brightness will result in a dark picture with only dots of light showing. In this mode, the true appearance of the street is captured. The camera automatically sets the optimal shooting settings.

Turn off Continuous AF (auto focus) to prevent recording camera noise during video capture. When you turn off Continuous AF, you may notice a narrower area of focus or depth of field, especially if you zoomed to a telephoto position before recording. Turn the Mode dial to Video, then press the Menu button. Highlight the Continuous AF menu, then press the OK button. Highlight Off, then press the OK button. (On is the default.) Press the Menu button to turn off the menu screen. This setting remains until you change it, change the Mode dial, or turn off the camera.
