The focusing speed of iPhone6 camera is super fast. What technology is used?

In photography, high-speed photography has always been a technique used by photographers to capture wonderful moments. However, high-speed photography is not enough. Without proper high-speed photographic equipment, people can only expect. Therefore, the shooting machines on the edge of the stadium and in the hands of journalists are high-speed shooting equipment. So if we are not journalists and want to try high-speed shooting, what kind of camera can we choose? 20 15 camera with the fastest focus and the most worth buying Recommended model: Sony? 6000 (information market photo forum) model features: 4D focusing, 1 1 frame/second continuous shooting speed, the fastest focusing micro-single TM camera reference price: 4099 yuan (with 16-50mm lens) a6000 was released by Sony in the spring of 20 14. In terms of price, it has also become one of the 4000-level cameras, and its competitiveness is quite strong. Click on the picture to see Sony? Details 6000 Sony micro-single TMa6000 combines the characteristics of NEX-6 and NEX-7. The overall shape is biased towards NEX-6, but the detail is NEX-7. The double turntable design at the top of the machine does not protrude from the top of the machine. One of the turntables is a model turntable, and the fuselage is plastic, so it is very light. In addition to black, a silver version and a black leather handle are also available. The handle is specially designed, which is more suitable for hand shape. So the grip becomes more comfortable and very close to the hand. Click on the picture to see Sony? Details 6000 Sony micro-single TMa6000 is a luxury product at the same price, with electronic viewfinder, folding screen and continuous shooting speed of 1 1 frame/second. It is an enhanced hybrid autofocus mode with the fastest focusing speed in Sony micro-single TM camera, with seven custom keys, and of course, Sony's almost universal WiFi wireless transmission and NFC connection methods. In addition, the sensor also adopts a brand-new Exmor APS HD CMOS image sensor with about 24.3 million pixels, and adopts A7R's seamless chip lens and lens position matching technology, which improves the image clarity and color performance. Sony micro-single TMa6000 has 179 phase detection autofocus points, plus 25 contrast detection autofocus points, and the whole picture is almost covered by the focus point. Such a high focusing density can't be achieved by any other camera. Sony claims to be the fastest focusing Sony micro-single TM camera, which can reach about 0.06s at the earliest. In fact, we can find that this is not bragging, but it is really much faster. Last year, when we conducted the annual evaluation of the mirrorless camera, the focus level of the Sony micro-single TM camera NEX-5T was in the middle and lower level, but the autofocus speed of the a6000 lens was obviously improved by several levels. In the forefront of interchangeable lens cameras, the performance is close to the M4/3 camp with the fastest focus. Moreover, the latest 4D focusing function can quickly predict the next action of the target object through the optimized autofocus algorithm. Simply put, by monitoring the speed of the moving object position, the 4D focusing system can predict the moving trajectory of the object, so as to focus the object in the shortest time. AF has better performance in following the focus. Fast-moving objects can continue to follow the focus, and automatically exclude objects that suddenly enter the screen. Keeping focusing on only one object helps you grasp the decisive moment. The high speed and accuracy of 4D focusing is the biggest guarantee for high-speed shooting of Sony's advanced micro-single TMA6000 focusing system. By combining AF-C continuous autofocus? District? For the focus selection mode, when the position of the subject changes greatly, it can still focus accurately. The above gif, which consists of 27 high-speed continuous shooting photos, shows the super focusing performance of A6000. Sony micro-single TMa6000 4D focusing proofs Editor's comments: Sony micro-single TMa6000 is a top APS-C format product named after the replacement model of Sony micro-single TM camera, but its core configuration is unambiguous, the image quality is obviously improved, and the focusing speed is also the fastest among Sony micro-single TM cameras at present. Coupled with the convenient professional configuration such as electronic viewfinder and folding screen, it is a premium product in terms of the price positioning of mainstream mirrorless cameras.

Recommended products: Canon 7D Mark II (information picture forum) Model features: 10 high-speed continuous shooting; -3EV low illumination focusing; Dual DIGIC 6 processors; Reference price: 9399 yuan (fuselage), just like the release of 7D in that year, 7D2 is still released, becoming the peak of the same level products. Equipped with 65 full cross focusing systems improved from 1DX, and the best real-life focusing system at present: full-pixel CMOS AF focusing technology, which has a high-precision shutter life of 200,000 times and a high-speed continuous shooting of 10 frame/second. All-metal body, four times the protection ability of 7D, brand-new viewfinder with 100% field of view, 20.2 million pixel APS-C CMOS sensor (same as 70D), equipped with dual DIGIC 6 image processors, and the sensitivity covers ISO 100-5 1200. It can be said that at present, 7D2 has no competitors at the same level. Click on the picture to see the details of Canon 7D Mark II. There is no doubt that 7D2 still follows the design of 7D, and the overall lines are more rounded, but it also gives people a full feeling. In addition, the overall appearance remains unchanged, but there are many changes in details, mainly to match the newly added functions of 7D2. In terms of volume, the volume of Canon 7D2 is about 148.6? 1 12.4 ? 78.2mm, almost the same as the previous generation 7D, and the size of the fuselage is no different from that of the Quan Huafu model, so it can be said that it is a giant in APS-C SLR. Click on the picture to see the details of Canon 7D Mark II. In terms of weight, 7D2 weighs about 9 10g (including batteries), which is indeed heavier than Quan Huafu SLR, at least much heavier than D750 and 6D. So all kinds of heavy feelings in my hands. Shooting for a long time is also a job that requires high physical strength. After all, the weight of equipment such as lenses has not been counted. Click on the picture to see the details of Canon 7D Mark II. Canon 7D2 uses an APS-C CMOS image sensor with 20.2 effective pixels, with a size of 22.4? 15mm, and two DIGIC 6 image processors are adopted, which can provide faster shooting and image processing speed, and its high-speed continuous shooting capability reaches the extremely high speed of 10 frames per second. In addition, the update of the focusing system is also the most powerful. It is equipped with the 65-point focusing system with the largest number of focusing points in the current SLR camera. The middle focusing point has a huge focusing brightness range of -3~ 18EV, and has a 17 custom focusing function option and six focusing modes. It can be said that this is almost the strongest focusing system on the market at present (well, there is still no focus &; Fixed point metering linkage function). Canon 7D2 real shot sample Judging from this real shot sample, the imaging level of 7D2 is higher than 70D. The improvement of detail performance and the level of high noise control are the most direct manifestations brought by DIGIC 6 image processor. Dual DIGIC 6 processors provide a stronger backing for shooting speed, storage speed and data accuracy. Generally speaking, the image quality performance can't be compared with Quan Huafu products, but it is very close. The main difference is that APS-C sensor is not as delicate as Quan Huafu sensor in detail, but this can't be seen without looking at the 100% big picture. However, in APS-C SLR, 7D2 is definitely among the best. Editor's comment: Canon 7D2 really stands at the peak of APS-C, and its performance, image quality and reliability are impeccable. So, what does Canon use for such a targeted product? Instant catcher? Describing it as 7D2 is to set a technical benchmark of flagship APS-C, achieve the best configuration of similar products, and give professional users better shooting support. Recommended products: Nikon D 4S (information market picture forum) Model features: 1 1 frame/second high-speed autofocus continuous shooting, ISO 409600, EXPEED 4 processor reference price: 39,500 yuan (single machine) Nikon D4S is Nikon's latest top-level SLR camera, and it has improved the maximum ISO limit and metering system on the basis of Nikon D4. Click on the picture to see the details of Nikon D4S. The appearance of Nikon D4S is the same as that of D4, which is a minor modification of Nikon D4. The whole fuselage has been lightened. 160? 156.5? The 90.5mm measurement weighs only 1 180g, making it a top-class SLR camera with excellent figure and weight. Lightweight settings make the fuselage easier to carry. Click on the picture to see the details of Nikon D4S. Nikon D4S is equipped with a new digital image processor EXPEED 4, a new Nikon FX CMOS image sensor, and has 65,438+0,623 effective pixels. The standard sensitivity ranges from ISO 100 to ISO 25600, and it also supports extended sensitivity as low as ISO 409 and as high as ISO 409,600. In addition, the accuracy of automatic white balance has also been improved, and even under such difficult conditions as artificial lighting, clearer color reproduction can be realized. In other respects, it is the same as Nikon D4, and it is a small modified product of Nikon D4. D4S focusing, metering and imaging system Nikon D4S adopts advanced scene recognition system, and uses 9 1000 pixel RGB sensor, which can study the brightness, contrast, color, highlight distribution of each shot scene, even including the existence information of human face. Then use this information to optimize the scene analysis, and analyze every image scene to be shot as accurately and quickly as possible before releasing the shutter, even high-speed continuous shooting. Group area focusing uses 5 autofocus points to focus at the same time. Compared with dynamic area autofocus with 1 initial autofocus points, it focuses on the target object more accurately like a net. It is especially useful when aiming at unpredictable and difficult-to-lock objects, while avoiding accidental background focusing. 3D tracking focusing has always been Nikon's focusing advantage. The same function, D4S will react faster than the opponent. Moreover, in practical use, D4S has a slightly stronger coke grasping ability. Real proof aperture: F2.8 shutter: 1/79 seconds ISO: 200 Edit Comment: Nikon D4S provides a better choice for professional users. ISO up to 400,000 is of little use to ordinary people, but for news sports reporters, in order to get enough shutter speed, it is urgent to use ultra-high sensitivity. Even at the expense of image quality, we must ensure the clarity of the shooting content. Coupled with the new metering system, the autofocus system has a better play in low light. Summary: All the products recommended above have high-speed continuous shooting function of more than 10 sheets per second. This speed can allow us to record more wonderful moments in life. The shot of 10 was shot at 1 sec, which is very practical compared with capturing the moment. Whether it's capturing beautiful women on the street, active babies or wonderful sports scenes, we can capture pictures that are not easy to shoot. I believe one of the cameras recommended above will suit you.
