What's your budget? For less than $500, you can get a pocket-sized digital camera with full manual controls, impressive photo quality, full HD video and a versatile zoom lens. If you want interchangeable lenses and even better image quality, expect to pay $800 or more.
Do you want a pocket-sized camera? Some advanced digital cameras can actually slip into a jeans pocket, while others are jacket-pocket sized. Interchangeable-lens compacts usually won't fit into a pocket.
Do you need a rugged camera? Higher-end digital cameras (above $750) are usually -- but not always -- made from tough, lightweight metal instead of plastic. The best interchangeable-lens compacts (above $1,000) are usually weather-sealed to keep out dust and rain. Waterproof cameras can actually shoot underwater, survive being dropped and more.
Do you want a viewfinder? All digital cameras have an LCD screen on the back. Some also have a viewfinder so you can hold the camera up to your eye to frame your shot, which feels more natural to some users.
How many megapixels do you really need? One of the top-rated digital cameras in our report has a 12-megapixel image sensor. Some offer 20 megapixels or more, which can translate to sharper detail if you blow up really big prints. Tests show that it doesn't always work that way, though, so don't judge by megapixels alone.
Do you shoot fast action? The speediest digital cameras can rattle off 10 full-resolution frames per second (fps) or more. Again, don't judge by the numbers alone: The best cameras have fast processors that can keep up with your trigger finger, but others leave testers twiddling their thumbs while the camera sluggishly records the images.
Do you want to shoot RAW files? Most cameras under $400 or so shoot only JPEG image files, which are pre-processed in the camera (edges are sharpened, grainy image noise is smoothed away, etc.). Some advanced photographers prefer to shoot RAW files and custom-process later on a computer, giving them total editing control. Digital cameras over $400 can generally shoot both RAW and JPEG.
Lenses cost extra, if you choose an interchangeable-lens camera. Usually, a versatile kit lens comes bundled with the camera (often a mid-quality 18 mm to 55 mm zoom). But the main advantage of these cameras is the swappable lenses -- you can attach a super-wide-angle lens, a long telephoto or a macro lens for close-ups. Expect to pay $200 to $1,500 per lens, depending on quality. The good news is that you can keep using your lenses even if you buy a new camera in the future, as long as you don't switch brands or platforms (both Olympus and Panasonic fit the same Micro Four Thirds lenses, for example).
