The d2x camera, from Nikon, has an excellent autofocus option that can be used to capture fast action. It has been designed in such a way that it can lock on to a target, keeping it in focus no matter what happens. This is great for taking pictures of one person on a basketball court, for example. It can be very hard to find this focus on your own because you need to have such a fast reaction time. You should use the autofocus function if things are happening quickly and could take you by surprise so that the shot is clear.

Extreme temperature conditions can damage a camera. A camera should never be left in freezing temperatures or extremely hot locations for any length of time.
