Apple has highlighted in the last few weeks some good practical examples of using the camera of the new iPhones [1, 2, 3], but nothing like tests done by users in general.
We have already seen a complete comparison of photos, now we go to some on video.
iPhone 6s vs. Sony a7RII in 4K
The iPhone next to a mirrorless which costs about $ 3,000. It is amazing how beautiful it is at normal zoom, but evidently when we approach the images we see how the Sony lens makes a difference in capturing details.
Hypnotizing video of a rehearsal made with an iPhone 6s and very cheap equipment. The comparative photos, in high resolution, can be seen in this post of Fstoppers.
Takes in 4K resolution captured with the iPhone 6s by Dom Esposito, from 9to5Mac. It gives a good idea of the power of the device.
