Optical vs Digital Zoom


On consumer digital cameras, the terms optical zoom and digital zoom are common. When shopping for a digital camera, ignore the digital zoom. What you should look for is the optical zoom capability, because what is captured using optical zoom is what the lens actually sees.
Digital zoom is basically using in-camera software to enlarge the center pixels in the photo, resulting in loss of detail and sharpness.

Some digital cameras use digital zoom exclusively, because they lack an optical zoom lens. On such cameras, the photo will be at its sharpest without using the digital zoom at all.
Other digital cameras have a combination of optical and digital zoom. On such cameras, I would turn off digital zoom entirely, and use only the optical zoom. This will ensure that I get sharp photos all the time.

  7. Most camera's have both, right? I mean, optical zoom to a certain degree, and if you want to zoom in even further, it goes to digital.
