A detailed but easy to digest analysis of the iPhone 6s's new camera including comparisons to the iPhone 6 by photographer Austin Mann. There are for sure, very clear improvements here, but by far the most dramatic is the iPhone 6s Plus's ability to optically stabilize video (previously OIS was for still images only) in all video formats — including 4K, time lapse, and slo-mo.
Optical Image Stabilization (OIS) for video is hands down the most significant improvement in the iPhone 6s Plus camera upgrade. The 6 Plus has OIS for stills (mainly helpful with low-light photos), but it wasn’t active when shooting a video or time-lapse. Now, with the 6s Plus only (not the 6s), we have active stabilization of all video and time-lapse content and the improvement is dramatic.
The time-lapse piece at the top utilized the Optical Image Stabilization significantly. The ability to create stable time-lapses anywhere, anytime, opens up so many doors. I can't wait to see what everyone creates with this.
The difference is visceral and once again makes purchasing the Plus a no brainer for anyone planning to do a lot of visual work with their phone. 11. As Austin points out, Instagram's Hyperlapse (free) does a tremendous job of stabilizing video on iPhones that are not the iPhone 6s Plus, but it doesn't help you with slo-mo or actual time lapse videos, or for recording video with audio.↩
