iPhone 6 is the second phone to feature phase-detection autofocus, after the Galaxy S5

During the introduction of the new iPhone 6 and 6 Plus, Apple spend some time talking about the new 'Focus Pixels' in the latest iSight camera. Behind the fancy name, though, lies a well-known technology that is typically used in SLR cameras. It's a different focusing technique from what's traditionally used in smartphones, and it's called phase detection autofocus. Hearing the name of the technology, some of our readers probably remember that the Samsung Galaxy S5, launched earlier this year, became the first smartphone to utilize phase detection autofocus. Now, the iPhone 6 (and its bigger version, the Plus) becomes the second smartphone to join this club.
The vast majority of smartphones today rely on 'contrast detection' autofocus, which analyzes the amount of contrast between nearby pixels to determine which area should be in focus. The downsides of this technique are that it tends to be less reliable in low-light environments, and it can be a bit slower, compared to phase detection. On the other hand, phase detection autofocus works in a totally different way - it analyzes the light rays coming through the lens in order to determine which object should be focused on. It's a fairly complicated process, but the bottom line is that phase detection, and Apple's 'Focus Pixels', allow the camera to focus in on an object in a quicker and more reliable manner. The Galaxy S5 proved that the technology works quite well in the context of smartphones, as its benefits could be easily felt by users. Now, we can expect the iPhone 6 to push things even further with its own implementation of phase detection.

slowly slowly apple is taking things from samsung and android.... still they blame samsung for copy, quite ironic... if samsung has done it(like finger scanner) there will be a huge out cry that samsung is a copy cat.... anyway, this time apple really have nothing in their sleeves which they called innovation

Umm, yeah, not quite. I'm not rich, but carriers subsidize so it's quite easy to purchase. Besides, Apple products have always out performed Android devices despite Android devices having "higher specs". That clearly goes to show that Apple has a much more optimized system, especially since iOS is more fluid than Android with lower specs. The general childish ignorance in PhoneArena hurts my brain and either makes more people stupid by actually believing what most kids say here, or people come here for the comedy, because damn if it isn't funny reading comments about Android fans (not all) but many just want to bash Apple when they clearly haven't experienced how awesome it is, otherwise most would shut up about it. /done rant

most of them used it, thats why they know the short comings of ios and this is the reason they bash apple... I myself owned ip4 & 4s, thats why I bash apple bcoz it took huge chunk of money out of my pocket for such a low end device(thats my fault though bcoz I got ifo0led)... otherwise I wont even bother to educate people about apple

I'm a CDL Truck Driver, I carry a Note, soon to be Note Edge, and a iPhone, soon to be iPhone 6. One phone to do Multitasking, and the other for simple Apps, and telephoning. I'll let you guess which one i use for Multitasking. :)

yup, apple is copying with the phase detection and the 5.5 inch screen...what next, iphone with an spen? we already know about the notification center (android) and the fingerprint scanner (motorolla atrix)...and OMG, the back of the iphone 6 looks too similar to an htc. btw, all smartphones have rounded corners and some form of slide to unlock, but apple only sues samsung.

It doesn't make the camera bad, the camera is not affected by the way it focuses, the camera is affected by the size of the pixels and the lenses. In night time, lasers will always work better than determining the light coming into a lens.

You're absolutely right "the laser autofocus" is actually just IR assist lamp. It's pretty similar with NightFrame on my father's Sony DSC F717, it uses the infrared illuminators to let you frame your subject even in total darkness. But Sony DSC F717 also features hologram AF it uses a Class 1 laser to paint a grid pattern on the subject and is perfectly safe, even when aimed directly at someone's eyes.
