I was trying to find first tests and seems that the PC Magazine has done some laboratory level tests. If you find some other sites who has compared the camera's, leave a link. http://uk.pcmag.com/smartphones/845...us-vs-iphone-6s-vs-galaxy-s7-cameras-compared TL;DR The Verdict When comparing the main cameras on the iPhone 6s, iPhone 7 and 7 Plus, and Samsung Galaxy S7, the S7 wins out in our lab tests. Its larger sensor size gives it an edge as the ISO is pushed higher, and it scores the highest on our sharpness test. The iPhone 7 (and 7 Plus) come in a close second, with the older 6s trailing the pack. But, you can't discount the flexibility of dual camera modules, which is a feature that Samsung doesn't offer in its Galaxy line. The iPhone 7 Plus gives you the option of shooting at 56mm, and while you won't be able to benefit from the second lens in very dim lighting, it's a boon for use in daylight, especially for shots where a wide-angle lens is just too wide. It's early in the game. The 7 Plus's two-camera system is a work in progress. Apple is still working on the software required to capture images with a shallow depth of field using the dual cameras, and it will be interesting to see what other applications Apple and third parties cook up in the future.
