Phase-detection/ 425 contrast AF points w/ 93% image coverage.
The difference here is thatNikon has built in a sophisticated on-sensor phase-detection system.
Its 493 phase-detection AF points cover 90% of the image area and work in combination with a conventional contrast autofocus system.
There is one 48 MP f/2.0 wide anglecamera with a pixel size of 0.8 µm and phase-detection autofocus.
The revised sensor design uses a Fast Hybrid AF System,with 567 phase-detection autofocus points, for notably fast and accurate focusing performance.
Each of these can be read separately,thereby allowing them to be used for phase-detection autofocus.
The entire system is comprised of 325 points,of which there are numerous phase-detection points for faster performance that is beneficial to photographing moving subjects.
Introduced with the EOS 70D in 2013, Dual Pixel AF is thename given to Canon's proprietary on-sensor phase-detection technology.
Approximately 40% of the frame is covered by 49 phase-detection points in order to provide fast AF performance to suit working with moving subjects.
The focus on the a7II, just like the one on the a7,uses an autofocus system with 117 phase-detection and 25 contrast detection points.
Both a 65-point all cross-type phase-detection AF system and Dual Pixel CMOS AF technology benefit fast, accurate focusing performance for both optical viewfinder and live view shooting.
The sensor's design also provides Dual Pixel CMOS AF,which offers quick and accurate phase-detection autofocus for multimedia use.
In addition, the 800D's viewfinder-based phase-detection AF system has also seen a major revamp and now employs 45 individual AF points across the viewfinder, all of which are of the cross-type variety.
The Sony A6000 uses a modified high-resolution 24.3 MP sensor,with 179 on-chip phase-detection points that cover almost the whole area of the sensor.
Adopting the same hybrid autofocus(AF) system as the Z 7 and the Z 6, the Z 50 comes equipped with one of thefirst Nikon CMOS sensors that incorporate phase-detection AF.
The previous generation Galaxy Ssmartphone also had focus pixels for phase-detection AF, but those were way fewer- less than 5% of its camera pixels were used for focusing.
Without a doubt, one of the biggest upgrades and reasons to move up to the A6000 from lower-end and previous-generation NEX models is the newHybrid AF system with a whopping 179 phase-detection points.
It also relies on a precise but slow contrast-based autofocus system,as hybrid on-sensor phase-detection AF has yet to make it on to these bigger sensors.
This updated Fast HybridAF System employs a combination of 399 phase-detection points and 425 contrast-detection areas for quicker acquirement of focus in a variety of lighting conditions, and also maintains focus on subjects more effectively.
Indeed, Canon claims that its latest iteration of DualPixel AF is the fastest on-sensor phase-detection technology currently available to DSLR users.
As each of the 24.2 million pixels functions as a phase-detection sensor at the same time, high-speed and high-precision phase-detection AF is possible across a wide area that covers 80% height x 80% width of the image sensor.
This imaging system is benefitted by the Intelligent Hybrid AF system,which uses both contrast- and phase-detection methods to acquire focus quickly and accurately.
Fast Hybrid AF System-The Fast Hybrid AF system utilizes both a 179-point phase-detection system and 25-point contrast-detection system to achieve precise focus in as little as 0.06 sec.
Benefitting working in a variety of shooting situations, a heightened hybrid autofocus system now utilizes 91 total points,including 49 phase-detection points, for quick, accurate focusing.
The Cyber-shot RX 100 VI can capture 4K HDR video,has fast auto-focus with 315 focal-plane phase-detection AF points, has a sensitivity range from ISO125 to ISO12800 and can shoot continuous bursts at 24 frames per second.
Approximately 50% of the width and75% of the height of the imaging area is covered by phase-detection points, too, to offer greater compositional freedom without sacrificing fast autofocus performance.
Matching the speed and imaging capabilities is the apt Multi-CAM 20K AF system,which features 153 total phase-detection points, including 99 cross-type sensors for improved subject recognition, and 55 of the points are selectable for greater compositional freedom.
More importantly, perhaps, this new sensor uses Canon's Dual PixelCMOS AF sensor to deliver fast phase-detection autofocus even in Live View mode, so Live View and movie autofocus should be faster and smoother than the EOS 6D Mark I's older and simpler contrast autofocus system.
