Well I found out about afterfocus in the HTC get started setup.
After focus is quite buggy though.
How does Sony's Background Defocus and Nokia's app do this, without a depth sensor - it's visually better than the m8 too :0
Though the app works on the Xperia S with the z1 camera with its z2 defocus app.
Basically, this defocus thing is possible on all devices without a depth sensor - but has a auto focus camera (which nearly all do ). The z2 takes pictures at different focus points and combines them once you choose your area to "have focus"
