I couldn't find a full review on the camera but I looked at the specs. The minimum focus distance is 10cm, so be sure you're not getting any closer than that. With the lens zoomed out try aiming the camera at something that is approx. 10-12cm away and has lots of detail and contrast (not smooth and of a single color). You should be able to get it in focus. When it's in focus try zooming in and refocusing on the same subject, with the camera the same distance.
When you're checking focus just press the shutter release button halfway to engage the autofocus-- once the af has locked on you can take the picture. If the af was locked on and the picture is blurry then you have a different issue- one that a tripod will solve or else faster shutter speeds.
