This is the focal point of stop motion - the very means of creation! It enables the artist to make something move or emote where normally it could not. There are a number of options to choose from depending on the project. Many people start out by making what is called 'brick films', or animations using Lego as the medium. In this case, a simple point-and-click style camera would do just fine! The only real consideration to be aware of in using lower-end equipment like this is to find one that has a setting to switch off lighting corrections. If the camera is constantly adjusting its exposure limits on its own, the end result will be inconsistant. Professional cameras offer this feature by default, as well as a manual focus which, again, will give a cleaner, more smooth-looking animation. This page is dedicated to a couple of my personal recommendations.
