This feature fixes onto the main subject and enhances focus on a snap's hot spots

An estimate of how long the battery lasts before needing recharging, based on standard tasks and usage

The amount of frames per second that can be shot in continuous shooting mode, useful for fast moving subjects

Can connect to a compatible digital camera to print without the need to use a computer.

Automatically detects faces and optimises focus, so they're the main subject of a snap

Allows your camera to detect and record where a picture is taken, perfect for holiday snaps

Stores files like videos and images, and programmes such as games. A portion of this may already be allocated to data like your operating system

Irons out blur and shake, so your shots are super-sharp and your videos are stable

Measures the lens' light exposure. This affects the depth of field (the distance beween the nearest and furthest objects that can be kept in focus)

The distance from the sensor and the optical centre of the lens when focused to infinity. A smaller focal length will generally result in a wider angle of view

Enables extreme close-up shots of small subjects like insects or plants

Defines the sensor's light sensitivity and therefore performance in low light settings. Greater ISO numbers indicate more light sensitivity, though may lead to more grain or noise in the image

Devices with NFC (Near Field Connection) can be tapped together to establish a wireless connection for sending or streaming files and other data

Reduces red-eye effect in portraits and group photos

The size of the device's screen, usually measured diagonally in inches

Delays taking the picture for a few seconds, ideal for self portraits or group pictures

The amount of time is takes for the shutter to open and close. High speed lets you freeze action completely, slower ones allow motion blur

The interface you look through to compose and focus your picture. Not all modern digital cameras will feature a physical viewfinder as well

Unpackaged weight of the product

Enlarges video captured by the optical zoom and makes it seem even closer. This involves zooming in on an existing image, so it gives slightly less detailed results than an equivalent optical zoom

Allows you to zoom the image closer to the subject. Optical zooms feature physically moving lens components, so it maintains the image quality as you zoom in. Digitial zooms essentially crop an existing image, so may lose image quality as they zoom in
