Hello folks

After all that head banging ,i finally landed up with FZ15.
last week only i got it

In low lights(its a cloudy day) at 12x optical ,the image is getting blurry...i dont know ..why..?
i have the OIS got tested both in mode1 and mode2(2 modes -still blurrry)

is this a camera problem or should i have to tweak..some thing..?

Also last week only i got the camera.
i dont know whether it works fine or not?
to my testing ,it look awesome...
are there any more things i need to ensure....?((just incase if i need to return and get a new one if there is any other problem))

any help or suggestions is greatly appreciated

Thank you
