Point and Shoot Digital Cameras That Will Revolutionize The Way You Take Pictures

A point-and-shoot camera or compact camera. It is a still camera designed for simple operation. These cameras use focus free lenses or autofocus for focusing. They use automatic systems for setting the exposure options. These cameras have flash units built in.

Point-and-shoots are the best selling cameras. They are as popular as camera phones. They are popular with people who don't consider themselves photographers but want an easy to use camera. They can use these cameras for vacations, parties, reunions and other events.Compact cameras are designed to be tiny and portable.

They are particularly suitable for casual and snapshot uses. The smallest, are generally less than 20 mm thick. They are described as subcompacts or "ultra-compacts" and some are nearly credit card size.

These cameras incorporate a retractable lens assembly. This allows a thin camera to have a moderately long focal length. These cameras fully exploit an image sensor larger than the one on a camera phone. They have a mechanized lens cap to cover the lens when retracted. The retracted and capped lens is protected from keys, coins and other hard objects. Making it a thin, pocketable package. Subcompacts commonly have one lug and a short wrist strap which aids extraction from a pocket. Thicker compacts may have two lugs for attaching a neck strap.

Compact cameras are usually designed to be easy to use. They sacrifice many features and picture quality for compactness and simplicity. Images can usually only be stored using lossy compression (JPEG). Most have a built-in flash usually of low power, sufficient for nearby subjects. Live preview is almost always used to frame the photo. Most have limited motion picture capability. Compacts often have macro capability and zoom lenses but the zoom range is usually less than for bridge and DSLR cameras. Generally a contrast-detect autofocus system, using the image data from the live preview feed of the main imager, focuses the lens.

These cameras incorporate a nearly silent leaf shutter into their lenses.For lower cost and smaller size, these cameras typically use image sensors with a diagonal of approximately 6 mm. This corresponds to a crop factor around 6. This gives them weaker low-light performance. These cameras have a greater depth of field, generally closer focusing ability, and smaller components than cameras using larger sensors.

Starting in 2011, some compact digital cameras can take 3D still photos. These 3D compact stereo cameras can capture 3D panoramic photos for play back on a 3D TV. Some of these are rugged and waterproof, and some have GPS, compass, barometer and altimeter.
