iSight Camera. The you-can’t-believe-it’s-on-a-phone camera.
The iSight camera 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. It 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. The iSight camera gives you 8 megapixels — that’s 60 percent more pixels than the camera on iPhone 4. And 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. 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. 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.
iOS. The world’s most advanced mobile operating system. And the easiest to use.
With every iOS advancement come even easier ways to do everything. That’s what makes iOS years ahead of anything else. iOS 5 leaps even further ahead, bringing over 200 new features to iPhone 4S. Here are just a few of our favorites.
iCloud. Your content. On all your devices.
iCloud is the easiest way to manage all your stuff, because it manages it all for you. iCloud stores your music, photos, apps, mail, contacts, calendars, documents, and more. And wirelessly pushes them to all your devices. It’s automatic, effortless, and seamless. And it just works. With iCloud, the music you buy in iTunes appears automatically on all your devices. You can also download your past iTunes purchases. So your music collection goes where you go. With Photo Stream, you can take a photo on one iOS device and it automatically appears on all your other devices, including your Mac or PC. Your photos show up, just like that. And you can show them off everywhere. iCloud can automatically keep your presentations, reports, and other documents up to date across all your devices. Even when you update them, they're updated in the cloud automatically.
FaceTime. It’s even better face-to-face.
FaceTime lets you hear a voice and see the face that goes with it — iPhone to iPhone, iPad 2, iPod touch, or Mac over Wi-Fi.5 So no matter where they are, no matter where you are, you’ll always be there. Making a FaceTime call is just as easy as making a phone call. And it’s even easier with Siri. Just tell Siri “FaceTime with Mom” and you show up, smile, and wave hello. You’ll never miss a big event, an important meeting, or a good laugh. And who wouldn’t be happy to see your face?
Retina display. Clearly remarkable.
The sharpest, most vibrant thing you’ll see on iPhone 4S is everything. The Retina display is the highest-resolution phone screen ever. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. But without a doubt, you’ll notice crisp text, sharp graphics, and stunning images. It’s more remarkable than the printed page. And you’ll be completely absorbed.
