Comparing iPhone 6s/6s Plus in low light


Ben Lovejoy for 9 to 5 Mac:

Again, viewed on the phone and at iPad size, the 6s shot looked noticeably cleaner (look at the sky around the Shard, top left). But again, when we look at 100% crops, it's because the stronger noise-reduction on the 6s is simply wiping out detail. Look at the latticework in the arched arcade lit in yellow, for a good example. The 6s shot is noticeably less sharp due to the greater level of noise-reduction applied by the phone.

This is a good overview of the differences between cameras and impact of moving up to 12 megapixels. The key part for me was how the camera fairs in low light. Basically, it seems the iPhone 6s/6s Plus offers improved image quality and resolution, however, in dark areas image sharpness can suffer as a result of packing more pixels into the same sized optics.
