Most of the digital cameras within the mid-priced range include a 3x/4x lens - the first number refers to the optical zoom with the second number referring to the digital zoom. Optical zoom matters more in a digital camera.

The zoom that should be used for comparing cameras is optical zoom, and not digital zoom or total zoom. A camera’s quality depends upon the value of optical zoom; a camera with higher optical zoom is better than a camera with lower optical zoom.

In fact, today the digital camera manufacturers have started using a new term - “total zoom.” At best, it can be used to indicate the fact that a digital camera has both kinds of zoom - optical zoom and digital zoom.

Individuals who previously used the 35mm camera or an APS camera used only optical zoom. Digital zoom are associated with the digital video cameras.

Many photographers do not really associate digital zoom as “zoom” in the digital cameras, as it only enlarges a portion of the image. This particular zoom maintains the image quality by avoiding interpolation of the image. However, smart zoom works only if you select an image smaller than the full available image size.

Sometimes optical zoom is compared to resolution while buying a digital camera. There is also a tendency today to disable digital zoom.
