Here’s a small camera comparison with several of the phones we had lying around in the office! We tested in 3 different conditions: Low light, Natural Light and landscape scenery. We also tested the autofocus by shooting after the first tap to focus, no matter if it was blur or not. The phones we tested were: The Samsung Galaxy S5, Samsung Galaxy S4, Samsung Galaxy Note 3, Sony Xperia Z1 & iPhone 5S. We will be adding the Lumia 1020 when we can get our hands on one. (Chapree was out of office). All cameras were tested on full auto mode, no manual adjustments made.
EDIT: Initial test with the Z1 was with a smudged lens T_T. I have tried to reproduce the test after cleaning the lens so it won’t be exactly the same. I will leave the old pictures up for the sake of transparency.
