The camera in the iPhone 4S is going to be better. We suspected as much, but now we know exactly how it's going to be better.
It's faster. Much faster. We're talking half a second in between photos, so if you missed the moment you won't have to wait for an eternity for another try. Most of the other leading camera-phones take two to three times that long.
It's bigger and brighter. The images it takes will be 8 megapixels at 3264x2448 pixels. That's some nice resolution right there. But, as we've said before, ISO is as important as megapixels. Sometimes adding more pixels into the same, small area actually decreases the image quality if the sensor can't handle it. Thankfully, the image sensor is going to be backside illuminated (like the iPhone 4, the myTouch 4G Slide, and Sony's newer Xperia phones), which will get it 73 percent more light (more than the iPhone 4, too). In other words, photos you take when the lighting isn't great will suck less. It's got a larger, f/2.4 aperture, too, which isn't much bigger than the iPhone 4's, but it will give it another little boost.
