Hmmm....define "quality" for a zoomed in image. If you mean it looks sharp and un-pixelated like the unzoomed image, you must have started heavily zoomed out to begin with. Or you need [newer] glasses.

The digital zoom function does not give you any more data to work with, it just expands the existing image to fill the screen. Increasing the "zooming view" on your device is exactly the same as editing the picture after you take it. So, if your quality was good, just use your photo editor to crop the picture to the desired area and the net effect is the same as if you had a higher digital zoom function.

Close. "Native" Megapixels are a function of your hardware, and are typically the best "Quality" you are going to get. Some cameras (not these) can improve on native MP by using time information and some fancy image processing or sacrificing color depth. Most cameras get higher-than-native megapixels by interpolation, which gives a half-***** illusion of more pixels depending on the quality of the interpolation algorithm and the nature of the original image. It is sales trick bafoonery. "Digital Zoom" usually falls into the same category - instead of fabricating pixels between real pixels, they throw out the pixels on the edges and double or triple the ones in the middle. On most devices, it is identical to cropping and then stretching to original dimensions your final image. The only time "Digital Zoom" isn't pure crap is when color depth is sacrificed - then you really are zooming, albeit not without a penalty.
