Blurry images are rarely the fault of the camera but are instead caused by what is called camera-shake. Camera-shake is merely the small movements of the camera during image exposure. With fast shutter speeds, camera-shake rarely affects the sharpness of the image, but with slower shutter speeds, your photos will turn out blurry.
In order to prevent this, you will need to mount your camera to a Tripod or Monopod. A Tripod is much more stable than a Monopod, while a Monopod is easier to set up and move around. The two main parts, to all tripods and monopods, are the legs and the head.
As the name implies, a tripod has three legs. Each leg is adjustable to a specified maximum height, and by adjusting each leg to different heights, you can compensate for uneven terrain. Tripods come in a number of different sizes, and they are made with different materials. Depending on your needs, you will need to choose the appropriate size and what material it is made out of.
The name says it all. These are basically one leg (instead of three) that has the ability to expand to a specific height. A monopod is both portable and quick to set up. They are most often used in sports photography where portability and adjusting on the move is a must. Theses are made with the same types of materials used to make a tripod.
Tripod/Monopod Heads
The four basic types of tripod/monopod heads are ball, 3-way, pistol grip, and fluid head. The head attaches to the top of a tripod/monopod, has a threaded top that allows the camera to be attached, and has varying types of adjustments that allow for proper composition.
