The only one that counts is the optical zoom. This gives you the possibility to choose between wide angle and telephoto and any position in between, without loosing quality. The lens of your camera does the zooming, that's why there's no loss in quality.
Digital zoom means, that a picture taken with the highest optical telephoto setting is blown up, enlarged, and only part of it used. That gives an extreme telephoto effect. But the more the picture is blown up, the worse becomes the quality, as the pixels become visible. What a camera with digital zoom does you can also do with a picture on your computer. Don't pay a single penny or cent extra only because a camera has a digital zoom.

In an optical zoom, the various elements of the lens move in relation to each other to range from the wide to telephoto end - whatever the zoom range maybe. The digital zoom merely uses software to enlarge part of the image on the sensor. It should not be used. It is far preferable to crop. and then enlarge, in an imaging editing program.
