Galaxy S7 is the first phone with Dual Pixel autofocus, here's what it means

So, why did Samsung move from the already blazing fast phase-detection autofocus to a brand new Dual Pixel technology on the newly-announced Galaxy S7 and S7 edge. Not only is the 12 MP camera sensor a radical departure from the megapixel rat race we've seen on flagship phones for a few years now, but the whole camera module is brand new, with much bigger individual pixels, and a Dual Pixel focusing tech for the first time in a phone...

I was hoping, as Tyrion was, for at least a 1/2.3". That was the main advantage of nexus 6p camera. I was expecting them to match and raise a bit (for instance the f1.7). They remained in the 1/2.5". It's a shame. It seems that they are saving stuff for a mid-year upgrade (aka Galaxy Note). It makes sense for them to do so. They have to differentiate the Note from the "regular" S line. Or why would anyone bother to buy? Right now I expect the Note to present us the 6Gb RAM and some increase in sensor size.

It's not just about the size of the sensor, the Nexus 6P isn't exactly blowing us away with it's low light performance.

You can't beat physics yet. A larger sensor like 1/2.3" or larger would mean a bigger camera module= more protrusion, unless you go for a SLOWER aperture (than the f/1.9 on the S6 for example). That's why the 6P camera has to make do with f/2.0. And to put that into perspective, the jump from f/2 to f/1.7 gains you more than twice as much light (about 50%) as going from 1/2.6" to 1/2.3" with the same aperture (about 20%).

This is also very true and why Samsung gone with 1/2.5 and it as nothing to do with being cheap as some in here like to say, it's not, game of thrones man got it wrong

This is very true in the dark the auto focus take a very long time on all phone and then takes crap images, this is not the case for the s7, this is big as most images are taken when you with your mates I. Pub and clubs and in home and at work, I. Low light area, this is very big as in the past if you did this then normal day time images was crap like m7, in Samsung case they even killing the G5, it game over for the other phones when it comes to the cam, I be upgrading my 6 months old edge plus just for this on it own as all my images are always in low light in 98% of cases

You haven't even sniffed an S7, how the hell would you call it an abomination?

15. TyrionLannister unregistered

I called the sensor an abomination. The phone actually has pretty solid camera.

"You call it" ment for the sensor I guess. Auto-focus speed does matter if you want to catch the moment

It's less about adding speed and more about accuracy and covering more of the frame. OK LOL, it is a bit of waste of money. I don't think sensors genuinely need that many focal points in the frame but just enough frame coverage. I think going for software improvements in focus tracking makes more fiscal sense like Sony did. Samsung could've had the IMX240 enlarged, broadened the PDAF frame and called it a day even.

You are mistaking the sensor size with the number of pixels(megapixel count). The sensor of the S7 is same size as the S6, while they reduced the number of pixels(from 16 to 12). In return, the pixel size was increased from 1.15micron to 1.4 micron. Also increased the aperture of the lens to f1.7 (f1.9 for S6). Add to that the implementation of Dual pixel for better & faster focus & video. These combinations should help S7 camera make better, faster, cleaner images in all situations including low light & fast actions.

S7 absolutely destroys iphone 6s & galaxy s6 in low light image quality: Check how they shoot the same subject in low light: S7Edge:http://phandroid.s3.amazonaws.com/wp-conten​t/uploads/2016/02/Samsung-Galaxy-S7-sample-low-lig​ht-20160222_173921.jpg Iphone 6S:http://phandroid.s3.amazonaws.com/wp-content/up​loads/2016/02/iPhone-6S-sample.jpg S6 Edge:http://phandroid.s3.amazonaws.com/wp-content/uploads/2016/02/Samsung-Galaxy-S6-Edge-20160223_173824.jpg

Yeah I saw that too but if you see the actual video S7 is on a stand while the others aren't. That makes a big difference especially with iPhone which doesn't have OIS. https://www.youtube.com/watch?v=kL9JoBqI6IE

Understand, but then having OIS is an additional selling point for S7

25s picture on tthe s6 was much brighter then they minimised the app and the picture preview deteriorated greatly. Cheating, biased scumbags.

Unless the S7 was used in a long exposure mode (which doesn't appear to be the case), it can only make a difference for sharpness. Not for noise and brightness of the pictures.

Would be interesting to compare with Lumia 950.

I don't think I've seen PA do any comparisons in a while... I know I haven't seen any including the 950. I guess I'll have to check gsmarena or some other sites.

Guys watch this, my S6 is quite quick to focus but not like this. https://www.youtube.com/watch?v=rEblmHmKz3c

Ha, they never said anything about the front cam having the screen flash like the iPhone, love it

Yep, they're screwed if it's the real price. Was expecting 650 euros.

Hahahahhahaha, if that the price you soon see all the cheap lg users saying its a crap phone very fast, they was only support them as they was cheap But what I have noted if they do any new tech and not old tech like normal, I.e. Included ufs and sd820 and so on, they are very $$$$$$$ like Samsung, I.e. Take there oled TVs they cost crap loads

This just means Apple have to do a lot better in camera department to be on par of competition. iPhone 6s plus camera is really not great indoor..

stand vs no stand

You do see the screen right before they take the image getting load of light, what the stand got to do with the light going Into the lens before the image is even taken, all the stand will help with is the sharpness of the image, just take it as it is all other phone are crap next to the s7 and Samsung as done it again

I am spoiled by a great camera already with DNG for a long time. It shows nothing ground breaking to me. Though I haven't tested it, and may change my mind when we get one I was just pointing out that even though the other picture is darker, a stand makes a lot of difference if they wanted to use an app to 'brighten' it up. Though still wont equal the other. For the moment, I will say good job Samsung, I would have preferred a 1/2 sensor but so far its good.

This is about taking photos in low light, not focus. So the s7 kills the other two in low light. S6 comes in number 2 and will iphone has no chance.
