iPhone 7 Plus gets dual cameras (CNET News) By CNET
And, this is what we're doing on iPhone 7, plus it's plus a second camera. There's now two 12 megapixel cameras built in the iPhone 7 plus one has the wide angle, 28 millimeter lenses the same as the iPhone 7. The other is a telephoto 56 millimeter lenses, but why have to complete cameras with two lenses? Well to explain it? Let me show you a traditional, point-and-shoot or DSLR and how the lens can work. As you know, and we have many of these cameras in our lives, you can change the focal length of your lens to zoom in that's how we get a zoom feature and that works great. When you have a large camera where the big lens on it, you can move in and out that isn't so great on the lens you want to put in something that goes in your pocket or your purse. So how does it work the same as before you go into the camera app to take a picture, but now there's a new button right there on the screen.
Let me blow it up a teeny bit. It says one X it's right above the shutter and when you go to take a picture, it's using the wide-angle lens and taking a picture just as always, but now with this button you can do one of two things. First, you can just tap it, and it jumps to 2 X now you're, taking a picture with a telephoto lens you're, getting the same high quality, 12 megapixel picture or the beautiful optical lens. No software needed. The second thing you can do is you can put your finger on it and drag across it, and you can zoom from 1x to 5x as you go beyond 2x you're doing software zoom, but now, since it's starting with that telephoto lens the quality that image is four times better than before with software zoom.
In fact, it's so much better. We decided to push it even further, all the way up to 10x. So now.
