A truly well-deserved high-quality machine king, Sony A7RIIII+FE24- 105mm F4 hand-played.

Sony's A7 series has evolved to the third generation model. Although the design elements are similar, the evolution of mechanism and electronic performance of each generation has a refreshing feeling. Among them, the A7R series, which focuses on image quality, has reached the second generation A7R II. With Sony's exclusive BSI component technology, it has achieved overwhelming performance in image quality and high ISO. As the third generation of high-quality machine emperor, A7RIIII has also continued the same components, but there are also perceptible changes inside.

At the same time, Sony's A7 series FE mirrors have always lacked practical travel mirrors. Although there is a FE 24-240mm at present, the focusing speed and image quality are not ideal except for its huge size, and Sony has recently introduced a more eclectic and high-quality travel mirror FE 24- 105mm F4 G OSS. Being a member of the G series can't help but make people look forward to the performance of this new lens. This time I borrowed Sony A7R3+Fe 24- 105mm F4 from Sony in Taiwan Province Province. Trial combination.

The frame of the third-generation high-definition camera model A7R3 is the same as that of the high-speed camera model A9, and it is also the standard frame of Sony's third-generation A7 II series. Although it looks similar to A7II series on the whole at first glance, it can be found that the frame of A9 is designed except the turntable on the top left. In addition to adding dual SD card slots, fine-tuning some key configurations, and adding a touch screen and a joystick for focus selection, the biggest advantage of this border is the promotion.

Although the previous A7 series has the advantages of compact body, high image quality and universal switching, even if it evolves to A7 II generation, because the photosensitive element is larger than the previous APS-C, the mirrorless photosensitive element needs to work all the time, and the endurance of NEX system can't meet the needs of professional players, and the brand-new battery has increased its power by 2.2 times compared with the previous one, greatly improving the endurance of A7III, so it can also take out less batteries to use.

Another change is that A7RIIII also adopts A9' s new UI design, and previous users may need to be familiar with some projects with changed locations. In addition, this time A7RIIII also added a passive multi-shot composite high-quality mode based on the displacement of the photosensitive element, and used multiple shots as the unit of the element to synthesize, so that the effective pixels were superimposed into a photo of 65.438+69.6 million pixels.

However, compared with the superpixel mode of Pentax or Olympus with similar principles, A7RIIII has higher shooting restrictions and cannot be synthesized on the fuselage. It needs to input files into computer matching software, and it also limits the need to shoot static subjects on a matching tripod, not to mention that Pentax can provide hand-held shooting, but it can set the time difference of continuous shooting, and even be composed of multiple long-exposure photos, which is its characteristic. However, due to the troublesome operation, this technology was not filmed this time.

Although the photosensitive element is the same but equipped with a stronger focusing and computing engine, A7RIII uses A7RIIII's 42MP photosensitive element, but technically, with the help of the new engine, the performance is improved, and the image processing time is increased by 1.8 times, which can shorten the processing time of continuous shooting's rear fuselage, and the dynamic range is as high as 15(RAW required). There is also a 5.5-level fuselage to prevent hand shock.

However, these improvements are not as obvious as A9' s focusing system. A7RIIII is equipped with 425-point contrast and 693 phase focusing configuration, which also makes A7RIIII have focusing and focusing performance comparable to A9. Although there is no A9 crazy 20fps electronic shutter continuous shooting, it still has the level of 10 fps, and the mechanical shutter has surpassed the previous A7 series, reaching the level of 7fps.

At the same time, the electronic observation window continues the design of A9, using 3.98 million pixel organic light-emitting diodes, and the new optical design makes the magnification reach 0.78 times. At the same time, it supports the pupil focusing system, which can track the pupil of the subject in AF-C mode for high-speed focus tracking when shooting people. In addition, when using the electronic observation window, you can also move the focus with the touch screen (but I am still used to using the focus rocker ...).

A new type of travel mirror with mobility and image quality, FE 24- 105mm F4 G OSS, almost all 35mm film systems have 24- 120mm wide-angle to medium-focus zoom lenses except 24-70mm wide-angle to medium-focus zoom lenses, but Sony FE series has always lacked such lenses. The advantage of this focal length is that it can strike a balance between zoom magnification and image quality. At the same time, with the aperture of F3.5-f5.6 or F4 constant aperture, the weight is not too outrageous.

In the five years since A7 series went on the market in 20 14, Sony has finally introduced a high-quality tourist lens FE 24- 105mm F4 G OSS, which weighs 663 grams, has an ultrasonic motor and optical anti-hand vibration, and emphasizes the sharpness and resolution of full focal length. Different from other brands, Sony upgraded this lens to a medium lens.

High-quality, high-speed focusing, compact combination From Pokemon A7R to the third generation A7R III, almost every generation is upgraded with feelings. Of course, compared with the drastic changes from the first generation to the second generation, A7R II and A7R III have not changed much, but there is not such a big sense of jumping, but it is also because in retrospect, Pokemon A7R is actually not an excellent product, but a high-quality fuselage with high cost performance.

A7RIIII continues A7RIII's advantages in image quality and high-speed shooting. It can be said that with 24- 105 F4 G OSS, it is even more powerful. Lighter than G Master, more convenient focal length. Although the picture quality is somewhat different from that of G, it is better than Pokemon's FE 24-70 F4 ZA OSS. It can be said that it is an excellent combination of one machine and one mirror with A7RIIII, emphasizing high image quality.

At the same time, A7RIIII is not only a high-quality model that can only be used in the studio or with a tripod. Thanks to the evolved focusing system and engine, even ordinary sports photography and night shooting have strong performance, and it is hard to imagine that this is the level of a high-density component with high ISO performance. At the same time, after the A9 focusing system is introduced, not only the focusing speed and focusing performance change, but also the focus distribution is more flexible.

However, A7RIIII still has some lingering thoughts on dark focusing performance. For A7III, a camera with contrast focus only designed for video recording and low light shooting, A7RIIII's dark focusing performance is still not as good as A7III's, and there are still focusing problems in too dim environment. At present, the dark focusing performance of A7III is still the best in the whole series.

In addition, in continuous shooting, although it is not as crazy as A9' s 20fps, the continuous shooting performance of 10 fps and the highest 77 42MP photos are still quite strong. However, it is worth noting that due to the design of photosensitive elements, when shooting high-speed moving objects such as racing cars and high-speed trains, it is impossible to have strong shutter distortion suppression like A9. After all, A9' s photosensitive element is naturally optimized for sports photography, which was also given to these two models by Sony.

The unshakable king of A7 family's comprehensive performance.

Including A9 series and A7 III released earlier, A7R3 is still the king under the current comprehensive performance, including focusing, focusing performance, image resolution and so on. It can be said that it is an outstanding performance in the A7 family, and it also supports advanced 4K video recorders compatible with professional video formats.

Of course, for photographers, the same focusing system, but A7 III with only 24MP and lower resolution is also a good choice. However, the A7III's 42MP performance will never be disappointing for professional groups that stress extreme image quality, especially those who need large-screen output. In addition to Sony's own lenses and other brands' lenses, even the branch factories have successively introduced high-quality lens groups with native FE rings, and Gensonnie A7III series players have more lens choices.

Compared with the previous generation A7R II, A7RIIII still has its advantages, including dual-card slot, large-capacity battery, more evolved focusing system and higher image quality obtained by advanced engine, which A7RIIII can't reach, especially when the subject is not limited to static, A7RIIII can meet such strict requirements with the blessing of high-speed focusing system.
