Everybody wants a digital camera these days. They are cheaper than ever and since you just need to buy a memory card one instead of buying film and then paying for photo processing many times, the total cost of taking pictures is probably lower than it ever has been.
It can be a challenge to navigate the digital camera landscape since so many different models in so many different styles are available. In general, cameras fall into three groups: Compact cameras, semi-compact cameras, and Digital SLR cameras.
Compact cameras are the smallest and most portable style of cameras. Usually they are a small rectangle like a mobile phone. In most cases, the lens extends out when the camera is turned on and disappears again when the camera is turned off. These cameras are best for tossing into a pocket or purse. Years ago, it was necessary to make a trade-off between compact size and image quality but these days even the smallest cameras can take beautiful photos. They have some degree of customization, but it can be challenging to use since the camera is so small with so few buttons.
A semi-compact digital camera is larger than a compact camera. They may fit in a pocket, but not as unnoticeably as smaller cameras. typically the lens does not fit all the way inside the camera. They offer a higher degree of photo customization, but do not have interchangeable lenses.
Digital SLR cameras are the most expensive and most advanced style of cameras. SLR means Single Lens Reflex which means that a mirror is used to look through the lens to compose the picture. This mirror momentarily moves out of the way in order to take a photo. The biggest distinction of these cameras is that you can replace the lenses. Some lenses are meant for wide-angle or long-distance photography, while others are higher quality lenses. For all but the most dedicated photographers, it's most convenient to find a single lens that meets most of your needs so that you do not need to be constantly changing lenses while you are missing the action.
