not sure about all these camera spec. but what i found is
aperture size:
IP5s - f2.2
Z1 - f2.0
so f2.2 is bigger right? what does this means actually? what the advantage of having bigger aperture?
sensor size:
Z1 - 1/2.3"
IP5s - increased by15%... so how big is it?
with bigger sensor means capturing more light???
sorry, noob in photography
for aperture, the smaller the number denotes bigger the aperture size is. so f2.0 is bigger aperture.
the larger the aperture size is, the smaller the focus field is, giving a bokeh effect i.e. capturing portrait photo with blurred background.
if ip5 sensor was 1/3.2" and increased by 15%, a rough calculation will give 1/2.8"
base just on numbers, the z1 still has bigger aperture and sensor size compared to ip5s. lets see how the iphone perform in real applications.
