The zoom lens of digital cameras and camcorders is the ability to vary focal length and, thus the angle of view. Both digital camerasand camcorders have zoom capability. For the consumer this can beconfusing because there are two different types, known as Digital Zoomand Optical Zoom. When in doubt always go for optical zoom whenshopping for cameras and camcorders.

Itchanges the length of your camera lens and draws the subject closer toyou. Digital zoom has its place. It can be used if the only destination for your photos is to view them on your computer or cheap laptop computer,and send them via email. Photos online can be a much lower quality inthe camera and still appear acceptable when sent through e-mail orposted on a web gallery. But, if your goal is to print any of yourphotos you need a camera that has a high optical zoom rating and ifyour camcorder or camera also has a digital zoom function you shouldturn it off when taking those pictures. Your digital photography will be much better in the end, even if you are shooting from far away. Another important camcorder or digital camera shopping tip is to ignoredigital zoom ratings within optical zoom. Some vendors tout a hightotal zoom that includes digital zoom, and it is not the true OpticalZoom rating. Always look for the true optical zoom rating.
