Hi shoaflet and welcome to the Q&A Board Forum!
To best help, we need to know more information about the types of photos you're taking that are blurring? Low light? Bright light? When taking action photos, etc? What focal length (wide or telephoto)? What shutter speed?
My first question would be is if you are depressing the shutter release button correctly, in two steps?
Your camera has a FujiFilm Super CCD, so you need not be afraid to raise the ISO to 400 or 800.
Give us more information and I"m sure we can help.
