Sensors are larger than on typical point-and-shoots, meaning image quality is markedly better, and youre given the option of shooting RAW images, allowing additional possibilities when editing your photos. Canons PowerShot G16 ($550) is a popular model. Single-lens relfex (SLR) cameras: These are the cameras used by professionals. SLRs are often sold just as a camera body; the Nikon D600 body, for instance, costs $2,100. But if youre an amateur looking for a top-notch camera, you can find SLRs targeted at consumers, such as the Canon EOS Rebel T3 ($450, with a lens).

Demystifying digital camera sensors once and for all
Small sensors The last two sizes listed below make no practical sense. As a point of reference, these small-sensor definitions are derived from the size of video camera tubes used in CRT TVs circa the 1950s. 1/1.7 inch (7.6mm by 5.7mm): Among the largest sensor sizes used in compact cameras, these sensors allow larger pixels for improved noise performance over standard pocket point-and-shoots.Larger pixels more ably handle gaps in brightness to reproduce better image detail. 1/2.5 inch (5.76mm by 4.29mm):This size is among the smallest sensors, typically used in low-priced point-and-shoot models.
Digital camera buying guide
The most common CFA is the Bayer array; some CFAs have extra green-capturing sites, because green carries the most detail information (it's a human eye thing), such as Fujifilm's X-Trans, and Sigma's Foveon-based technology stacks the filters so that each pixel processes each color primary. Cheaper point-and-shoots still use CCD (charge-coupled device) sensor technology. Inexpensive CCDs don't deliver photo quality as nice as pricier CMOS sensors, but conversely, expensive CCDs like those used in medium-format cameras produce better photos. In general, CCDs are slow and poor for video. Light sensitivity A camera's sensitivity to light is specified as ISO sensitivity; the higher the number, the better the camera's ability to shoot in low light.
