Coming from a z1 which i hated with passion for various reasons (one being the poor camera performance) i can tell u it is at leazt a decent camera for a phone. Do not expect wonders coming from a mobile phone camera anytime soon. It performs quite nice out of the box and this is the point with mobile cameras... Capturing the moment. With z1 this was not possible cause its auto mode sucked very much and by the time u went manual mode to adjust the moment was gone.
Hit the thanks button if I helped you...
