I am not the best guy to answer this, as I dont like phone cameras very much and don't have very much experience, and I didn't test them side by side. From my experience both phones in good lighting conditions do good enough pictures for usage on mobile devices, XZ maybe have a bit more natural colour capture. If the light is poor or I need pictures for printing, result is not good enugh on both phones, for me OFC. On the negative side, XZ needs a lot of direct light to capture good pictures in macro mode, while SIII doesn't. On positive side for XZ due more memory or better system optimization camera stay on the same acceptable level of laginess even after sveral hours of multitasking with focus on video and image capture while SIII starts to lag horrible to the point of not beeing usable until phone restart. If you have idea what would you like to see as direct comparison and in no hurry, write me and I will see if I can help.
