2. All-new 8MP camera and optics 

This just might be the best camera ever on a phone. And with all-new optics, it just might be the only camera you need. Because behind every shot, you’ve got 8-megapixel resolution and a custom lens with a larger f/2.4 aperture. Not to mention an improved backside illumination sensor, excellent auto white balance, advanced color accuracy, face detection and reduced motion blur. That all means that no matter how many people, how much light and how much action you capture, everything looks exactly as it should. And just wait until you see the photos. 

8MP 

The iPhone 4S camera has 8 megapixels — that’s 60 per cent more pixels than the camera on iPhone 4. They’re engineered with a higher, full-well capacity to collect even more light. With more megapixels and more light, you’ll see a dramatic difference in the resolution and details of your images. 

All New Optic 

The custom lens uses five precision elements to shape incoming light, which makes the entire image sharper. The larger f/2.4 aperture lets in more light, so photos look brighter. And the advanced hybrid infrared filter keeps out harmful IR light for more accurate and uniform colors. 

Editing 

Touch up photos right on your iPhone — without the help of photo editing software on a computer. You can crop and rotate photos, enhance the image overall, and even remove red-eye.

Video Stabilisation
