If you compare to the Galah below, although the sharpness of the Galah is not perfect because of having no tripod, it is better than the sparrow. The technical details are all identical to the sparrow above. This was shot at 24x Optical Zoom. I had turned off the digital zoom after seeing the results with the sparrow - great to be able to see so close from a distance, but not what I want in a photo. My next step is to get a tripod to sharpen up my focus.

The second page also explains well.
Optical zoom is the one to work with for best results, but the digital zoom may well be useful if it is impossible to get close enough and a poorer quality photo is your only chance to get something at least. (I speak strictly as a beginner learning, not as an expert).
