The ability to magnify your subject for close-ups, or pull back for wide shots. Most current cameras include a variable optical zoom lens.
A camera's CCD consists of millions of pixels, each one building up a tiny charge of electricity in response to the light it "sees." The more pixels a CCD has, the higher its resolution.
The effective pixel count is the the number of pixels that are actually used when a picture is taken, because some pixels on a CCD don't get used for picture information. Effective pixel count is a more accurate way to assess a camera's capacity.

Most cameras these days can shoot detailed, high-def video in addition to still photos.
Cameras with image stabilization have technology built-in to counteract the blurriness that can affect handheld shots. Optical image stabilization corrects for movement mechanically, avoiding any picture degradation associated with digital stabilization.
Wi-Fi capable cameras allow easy uploading of your images to social media sites, without a computer. Some models offer additional features when used in conjunction with a Wi-Fi enabled smart device, including remote shutter release and scene monitoring on your device's LCD display. Other future applications may give you even more options with your camera.
