When you start out in digital photography, the first thing to consider is which type of camera you will use. There are many choices: DSLRs (digital single lens reflex camera), point-and shoot compact cameras and camcorders. Each offers different features and benefits. DSLR cameras, for example, offer superior quality images but are heavier and larger than other types. Point-and–shoot cameras can be smaller and lighter than DSLR cameras, and they often have automatic settings that allow for special situations. Camcorders offer excellent video recording capabilities, and may also have still photo shooting modes. Smartphones are small, light, and easy to carry around and offer great image quality and many advanced features such as GPS mapping, music playback, and Internet browsing.
Once you've made a decision about the type and model of camera you want, then you must decide whether you want to buy it new or used. If the camera was purchased in the past few years, it is possible to find used cameras at reasonable prices. Newer models cost more, as manufacturers spend a lot of money on developing new technology.
Next, you'll need to buy lenses. The quality of your photos is directly affected by the lens. They enable you to adjust the focal length of the lens so that you can zoom into the scene with no loss of focus. Some lenses can be equipped with flash units that are built-in, while others may require external flash units. Many brands offer many lenses with unique characteristics.
Finally, you'll need to buy memory cards. Memory cards are used to store images taken with your camera. Your card's size will determine how many pictures it can store. You will need multiple memory card if you plan on taking many photos.
