I can count at least twenty times now where I have gone to snap photos and the
lack of autofocus made for frustration.
The three most common
types of autofocus on cameras include contrast detection autofocus, laser autofocus, and phase detection autofocus.
The presence
of autofocus makes a big difference: you can finally put the focus on your face manually when taking a selfie instead of letting the phone decide.
The
lack of autofocus is also starting to emerge as a downside when some flagships are including the feature for their selfie cameras.
Without getting in to too much technical detail, it's a
type of autofocus that is relatively new to smartphones.
They also added a very large aperture of f / 1.7, increased the
speed of autofocus, offer live HDR and retained OIS, while the Nexus 6P uses the highly praised 16MP.
The Galaxy S II features an 8 megapixel shooter
capable of autofocus, LED flash, geo - tagging, touch focus functionality, face / smile detection, image stabilisation and 1080p video capture.
On the front there's a 2.1 - megapixel camera and on the rear there are 8 -
megapixels of autofocus LED flashing goodness.
In the front there's a 2.1 - megapixel camera and on the rear there are 8 - megapixels

Again lack
of autofocus in Video Recording for iPad 3 non mentioned, and a camera without the flash loose pretty easly in every low light conditions
Apparently, the update has significantly improved the performance
of the autofocus on the iPhone X, iPhone 8 and iPhone 8 Plus.
5 Megapixel EDOF Camera: One of the only real disappointments I have on the BlackBerry Bold 9900 is the
loss of autofocus functionality from the camera.
Apart from this, the camera range also includes video capture feature in 4K, burst shoot of 20 fps, the hybrid
system of autofocus, slow - mo of 1200 fps, and OLED touchscreen on the rear.
For instance, mirrorless cameras are closing the speed gap with DSLRs in
terms of autofocus, thanks to a new generation of phase - detect sensor models from Sony, Fujifilm and other companies.
The
addition of autofocus to the front camera of the Galaxy S8 may not be the main attraction of the upcoming flagship, but it will certainly be a great addition to the device, knowing that Apple has already done a similar move with its latest flagships, the iPhone 7 and iPhone 7 Plus.
The two devices also have a 5 - megapixel front camera, which too features an aperture of f / 1.9, which is a little narrower than the new devices and there is fixed focus
instead of autofocus.
It managed to score «only» 84 points in the video test, dragged down by the lack
of autofocus tracking capability in default mode, shadow and highlight clipping in high - contrast scenes, and residual motion when holding the camera still while recording.
Apple's new sensor will use different technology for the 3D system than the technology used by the TrueDepth camera system which will enable better depth detection for augmented reality apps, and a more accurate type
of autofocus for photography.
My impression was that
speed of autofocus was the main advantage of the Samsung, which isn't an issue for most smartphone photographers.
More significantly, the S7's front - facing f / 1.7 is
capable of autofocusing, a first for any front - facing smartphone camera.
Where the camera struggles with close - up shots (in the image below we hadn't even zoomed in — the fuzziness comes from a lack
of autofocus) it handles long - shots much better.
Huawei has also worked on the speed
of the autofocus.
They also added a very large aperture of f / 1.7, increased the speed
of autofocus, offer live HDR and retained OIS, while the Nexus 6P uses the highly praised 16MP.
HTC's really talking up the speed
of autofocus and the HDR Boost function, meaning you get the benefit of zero - lag HDR, so you should get great photos instantly with no messing around.
They also added a very large aperture of f / 1.7, increased the speed
of autofocus and retained OIS.
The cameras on the A7 are 13 - megapixel and 5 - megapixel snappers, the rear is capable
of autofocus, face detection, HDR and has an LED flash.
Razer swapped out my original review unit, and the replacement unit doesn't have
any of the autofocus issues I first experienced with the device.
