Asus zenfone is just like average mobile which comes at its prise. It provides 8 mp back camera and 2 mp front camera. Screen quality isexcellent in touch sensitivity aspect as well as visibility.
But zenfone 5 lacks in battery. It has 2800 mah battery which is not enough for smartphone with such functionality. I will reqest asus to look after that. Performance is so good it can easily handle heavy apps and games.
