I currently using Xperia Z3, which I upgraded from Z1.
My 1st criteria of choosing a smartphone is the camera, because smartphone is my daily camera beside my other Sony camera like A7, A6000 and RX100iii

So now I wonder which should my next smartphone be? Xperia Z5 or Galaxy S7....
because so many review have gave the camera on Z5 very bad comment!!

I went to Sony Centre to try out yesterday, can really feel the slowness while browsing the photos taken (I currently using Xperia Z3)
Camera also slow in focus and taking photo for both rear and front camera, keep getting blurry photo, even i set to high ISO at 1600
however i do like the big screen, surprisingly not too big to hold in one hand (I used to owned Galaxy Note 2)
must give a big big like to the screen edge design, really felt so nice to hold!!

Because my primary criteria of a phone is on the camera and photo viewing, therefore I have to switch my consideration to either Xperia C5 Ultra or M5
After viewed so many review, seem like M5 stand out on its camera (both rear and front) and price
However C5 Ultra come second, camera is just a bit behind M5

Any commend from XA Ultra, C5 Ultra and M5 owners? TQ

Totally agreed. Sony SteadyShot is the best especially in video shooting!
I dun mind with a little bit of cropping, but it does work very close to a steady cam!
The only thing that still holding me from switching out from Xperia phone (>_<)
