For me (the owner of both a Z3C and Z5C) the photos don't even come close to the quality of an iPhone. I don't have any objective measure for that, just my own experience - I will always use an iPhone if I can. Perhaps just as importantly, it takes at least four seconds for the camera app to activate and be ready to take a photo. Simply put, the software is awful.
