Compact

There are several different types of digital cameras. Compact and Ultra-compact are light, pocket-sized cameras that are easy to carry, usually with a built-in lens. Standard point-and-shoot cameras are of medium size, usually come with a built-in lens, and have basic features that are useful for the casual photographer. SLR/Professional cameras are usually larger, but offer more advanced features and detachable lenses for the photography enthusiast or professional.

16 Megapixel

The sensor in a digital camera is composed of pixels, which are tiny light-sensitive squares. The sensors in most cameras today are made up of millions of pixels, each one registering the brightness of the light striking it as the photo is taken. A megapixel is the term used for a million pixels — and the more megapixels an imaging sensor has, the higher the camera's potential resolution. On the other hand, the megapixels determine the size of the print, so higher megapixels means larger print sizes, for examples, 6 megapixels are good for 8 x 10 in. prints, 8 megapixels are good for 16 x 20 in. prints.

18x

The optical zoom ratio of a digital camera measures how much the lens can actually zoom in to make subjects appear closer. Be careful to not confuse optical zoom with digital zoom. Optical zoom actually enlarges a picture while keeping the resolution and sharpness of the picture high.

4x

Unlike optical zoom, digital zoom magnifies the pixels but not the actual image. The resulting image appears bigger, but is not as sharp as with an optical zoom.

16 Megapixel

Resolution is measured in megapixels. The higher the megapixels, the sharper and more detailed the pictures your digital camera can take, and the bigger you can enlarge them without losing the sharpness of the image. 3.1 megapixels and higher is usually considered sufficient for print-quality photos. Photos with a resolution of less than 3.1 megapixels are best viewed only on computers.

CCD

A CCD sensor will provide a sharper more precise image, but is generally more power consuming. CMOS sensors are generally more energy efficient and are creating better and better images as technology develops.

HD (High Definition)

Autofocus

4.06 - 73.08 mm

The distance from the center of the lens to the image of an object at infinity. At same size, the distance from copy to image is four times the focal length of the lens. This also applies to lithographic process lens as well. A 35mm SLR camera has interchangeable lenses that can range in focal length from around 7 to 17mm which are usually fisheye, 17 to 35 are considered wide angle. 50mm is called the standard lens as it has the same equivalent focal length as the human eye. Anything longer is a telephoto lens. Usually expressed in millimeters, smaller focal lengths result in wider fields-of-view.

Not Interchangeable Lenses

Higher-end cameras may allow you to separate the camera body from the lens, allowing you to interchange lenses for different types of photography.

The optical zoom ratio of a digital camera measures how much the lens can actually zoom in to make subjects appear closer. Be careful to not confuse optical zoom with digital zoom. Optical zoom actually enlarges a picture while keeping the resolution and sharpness of the picture high.

Raw Image

Many cameras include different settings to control photo resolution. The resolution of the pictures you take affects their quality as well as the amount of memory they utilize. Higher resolution results in higher quality, but takes up more memory.

HDMI

The method by which your camera will communicate with your computer or other video device. Different methods enable you to download photos at varying speeds. Make sure the interface you want is also compatible with the computer you want to use it with.
