Sony has announced a full -size mirrorless camera "α7 IV" in Japan.It was a model that was announced globally in October and was announced in the Japanese market.

The price and release date are as follows.The body alone (ILCE-7M4) is released on December 17 (starting at 10:00 on December 7) for around 330,000 yen (tax included), and the lens kit (ILCE-7M4K) is around 350,000 yen (tax included) in the spring of 2022.It will be released after that.

Authentic Standard α7 IV that has evolved significantly from α7 III.The body is equipped with a 33 -megapixel -illuminated CMOS sensor "Exmor R", and can record a photo of up to 7008 x 4672 pixels.The image processing engine is the same "BIONZ XR" as the α7S III and α1.The high response, such as a high -speed continuous shooting up to 10 frames/sec, and a buffer with more than 800 sheets in RAW + JPEG photos, will not disappoint the expectations of the α7 series users.

Regarding the AF = autofocus of the α7 IV, a newly developed image processing algorithm is adopted along with the flagship α1, and the AF point is 759.Now it is said to be "AF Sony", but there is another attention for AF.That is, in addition to the past people and dogs, it has become possible to track bird eyes.This is exactly the specification of hitting a bird watcher.And you can't miss the fact that three pupil AF mode can be used for the first time in the α series when shooting video.

The function of "focus map", which visualizes the focus area, is also added, and it is effective when manual focus or when using AF in a gimbal, such as blue, the subject in front of it is red.prize.In this way, not only AF but also users shoot using midfielder can see the detailed evolution.

In addition, a new feature called "Breazing Correction" that corrects the angle of view at the time of focus is installed as an α series.It cannot be used unless the lens side is a genuine product, but a more focus losing like a movie is possible.

The optical camera shake correction is the same as the α7S III 5.It is 5 steps, so I don't think a tripod or gimbal is needed even in handheld shooting.

For videos, when recording 4K videos in 30P, it is possible to output a high -resolution 4K video by 7K over sampling that reads all pixels.Shooting can be performed with 4K60p or full HD120P, and XAVC HS (MPEG-H HEVC/H).It supports 265) and 10bit 4: 2: 2 ALL-INTRA XAVC S-I, and seems to be able to use many video formats like the α1 and α7S III of Cinema Line cameras.

The α7 IV has become more attractive for both still images and videos, but I'm also worried about heat countermeasures.This is not necessarily used indoors alone, but the heat is a matter of life and death for outdoor schools who enjoy the bird AF.In the α7 IV, the overall heat that tends to accumulate in the camera shake correction mechanism is generally escaped, and the Sony says that opening the monitor is more effective than the state where it is closed.

The LCD monitor has been changed from tilt (α7 III) to vari -angle (α7 IV), and the angle of view has been changed from 4: 3 (α7 III) to 3: 2 (α7 IV).This makes the preview display on the entire screen (the width of the black belt that appeared up and down) said Sony officials.

It is also attractive that α7 IV can be introduced to web cameras that are spreading in recent teleworks.It also supports 4K15P USB streaming (UVC/UAC), so you can share and distribute with high image quality with α7 IV.

By the way, the fact that you can transfer still images and videos from α7 IV to smartphones is a familiar function with Sony cameras, but 5GHz compatible Wi-Fi and USB 3..High -speed transfer can be performed by using a cable corresponding to 2 Gen2.Of course, wireless transfer is also possible, but it will continue to maintain the Bluetooth connection, which was required to re -registration, so NFC (so -called one -touch smartphone etc. can be paired with smartphones etc. with α7 III etc.) Was omitted in the α7 IV.

In this way, the functions and specifications unique to the recent camera, which are said to be digital camera difficulties, are more likely to be used for the full -size mirrorless of all static artists, but also the full -size standard and video group mentioned at the beginning.
