A 10x zoom and 20x digital, with stabilization. The images are of good quality, of course match sas is a reflex or a hybrid can give. You can order the shooting to voice, or remotely with another smartphone / tablet. All applications are available from Google Play, which allows a lot of funny stuff (time-lapse ...).
