The smallest digital zoom of cameras of this type and age is 1x and the biggest is 120x. With a digital zoom of 7.2 times zoom factor, the Fujifilm FinePix JX550 has a quite big digital zoom compared to most of the other medium megapixel cameras that have been on the market for a comparable time to this camera.
We compared all the other 7.2x digital zoom cameras to this camera and we think because of their better review scores, the Fujifilm AX650, and the Pentax X-5 are also worth considering.
If you want a bigger digital zoom then you might want to look at the Sony DSC-W580 (10x and higher rated).
