Written By mobilephonebrand

 At the ASCII Club in ASCII, various series and special features that can only be read by members are updated daily.

 Today, the popular article of ASCII Club "Sony" α7ⅳ "actual machine review = α1, 7R and 7s, the ultimate camera!"I'd like to introduce.


 "Α7ⅳ" that appeared from Sony.This is the fourth generation as a full -size mirrorless standard model.The predecessor "α7Ⅲ" is a best -selling model that is not an exaggeration to say that it has accelerated the spread of full size mirrorless.It's interesting how it evolved from there.

It was released on December 17, but is currently in shorting.The mass retail price is 328,900 yen for only the body.A lens kit with "FE 28-70mm F3.5-5.6" will be released for around 350,000 yen after next spring.The lens in the photo is "FE 24-70mm F2.8 GM" (277,750 yen)

The size is completely renewed for the body design, and for state -of -the -art operability

 The body is slightly larger than the predecessor (even a few millimeters).The first thing you feel when you hold it is a good sense of stability.The grip has become large and the shape has been improved, and the hold feeling has been greatly improved.

The body size is 131.3 (W) x 96.4 (H) x 79.8 (d) mm, and the weight is about 658g including the media and battery.By the way, the predecessor "α7Ⅲ" is 126.9 (W) x 95.6 (H) x 73.7 (d) mm, about 650g.

The depth and shape of the grip depression are well familiar with your hands and are firmly held.

When viewed from the top, the thickness of the body has increased, and the size of the grip is slightly larger.

 The back liquid crystal was changed from a tilt type to a vari -angle type.Many of the camera enthusiasts can be seen on the lens optical axis, but the variability range of the variability type with a high degree of freedom is also attractive.He himself was a tilt -style school, but once he got used to the vari -angle type, he turned to a barrier angle.

The vari -angle LCD rotates 180 degrees, so it is useful when you want to adjust the subject of the subject while holding it on a tripod.

 The arrangement of buttons is mostly the same, but the shape and the depth of the stroke are improved, making it easier to operate.

The back is almost the same as the "α7SⅢ", and the shape of the button has been improved and the operation feeling has been improved.

The "AF-ON" button is bigger, and the multi-selector has a flat shape with jagged protrusions.Other buttons also have a deeper stroke and are easy to press.

 The video button was replaced from the back to the back of the shutter button on the top.It will be an easy -to -use arrangement for video shooting.

The video button moves after the shirtter button.Of course, it is possible to allocate it to other functions such as ISO sensitivity by customization.

 Equipped with a new lock -type dial that has been selected from the mode dial selected from the mode dial.In the past, the exposure mode for video shooting had to be changed from the menu screen, so this dial makes it easier to change the exposure mode in video shooting.

The newly established "Staint Picture/Video/S & Q Dial".It also has a lock function so it does not move by mistake.

 The exposure compensation dial on the right shoulder is changed to a single lock -type command dial, and various shooting settings are assigned.In other words, there are two on the front and upper rear portions, and the back wheels and a total of four command dials.People who want to pursue their own operability are likely to be useful.

It has been changed from a conventional exposure compensation dial to a normal command dial, improving customization flexibility.

 EVF resolution has also improved from 2.36 million dots to 3.68 million dots.It wasn't enough to be dissatisfied with the predecessor, but it was still pleasant to look into high -definition.

EVF with improved resolution.Although the details of the eye sensor are also changed, the lower part has been changed from the top.

 The media cover has been changed to a slide lock type, and both slots are UHS-II.In addition, one slot can now be used with CFEXPRESSS TYPE A.

The upper slot is also SD and CFEXPRESSS TYPE A.The corresponding media is written on the back of the cover.

 The menu screen has also been updated to the latest array.There are some items that have been greatly changed, such as moving from "Setup" to "Shooting" tabs, but they are organized for each function and support touch operation, so if you get used to it, it will be easier to use than before.

Since the menu screen corresponds to the touch operation, the setting changes can be performed smoothly.

 The terminal cover on the side is changed to a type that can open and close firmly, and the HDMI has a standard terminal.

Equipped with standard HDMI terminals that were only high -end models such as "α1" and "α7SⅢ".This is perfect if there is a synchro contact, but is it terrible to ask for a standard model?

 There is also a function to close the shutter when the power is turned off to prevent garbage and dust from adhering to the image sensor.However, the shutter is as delicate as the shooting element, so care must be taken when handling.Personally, it is safer to clean it frequently, as it is exposed.

The notes are displayed on the screen that sets the function to close the shutter when the power is turned off.Certainly, the shutter curtain seems to be quite important in the state of the kiri.

 When you touch the body, the grip and operation buttons are used from the "α7Rⅳ", and the touch operation of the vari -angle liquid crystal and menu is "α7SⅢ", and the improvements used in the upper model are seen everywhere.Thanks to that, when I was actually shooting, it felt like a higher -grade model.

What is the effect of increasing the number of pixels by 38 %?AF speed improves

 The standard pixels of the full -size standard model had a long time around 24 million pixels, but the "α7ⅳ" increased to 33 million pixels.The difference between 800 pixels is not overwhelming, but when expanded with a moderate sharpness, the details are clearly resolved.The reproduction of the light and dark difference is smooth and the gradation is abundant.

The height of the resolution is transmitted from the texture of the statue and the depiction of the vegetation.Used lens FE 24-70mm F2.8 GM, aperture F8, shutter speed 1/250 seconds, ISO100, White Balance Auto, D Range Ottote Mizer Auto Creatock Standard Correction All Auto.

Even in the backlight of the sun, the gradation of the light and dark part is widely reproduced.Used lens FE 24-70mm F2.8 GM ・ Aperture F16 ・ Shutter speed 1/80 seconds ・ ISO100 ・ White Balance Auto ・ D Range Ottote Mizer Auto Creatock Standard Correction All Auto.

Since the aperture is a proximity shooting, the lens depiction is a little sweet, but it is fully resolved even if it is expanded.Used lens FE 24-70mm F2.8 GM, aperture F2.8, shutter speed 1/5000 seconds, ISO100, White Balance Auto, D Renge Otti Miser Auto Creatock Standard Correction All Auto.

 With a very high -pixel model, you may be worried about the lens performance ara and a little blur and focus, but if you have about 33 million pixels, you can enjoy shooting without much care.It may be the right pixel number for those who are reasonable than high -pixel models and are not enough with 24 million pixels.

 In the case of continuous shooting, both mechanical and electrons do not change in 10 frames per second, and motion distortion occurs with electronic shutters.The AF is a little, but it feels like it's one -tenpo faster.Tracking also reduced the loss when biting the subject was reduced, and once captured, he followed me.

Continuous shooting of the train coming in by tracking.If you are a regular movement subject, there is no need to worry about AF.Used lens FE 70-200mm F2.8 GM II, aperture F2.8, shutter speed 1/800 seconds, ISO100, White Balance Auto, D Range Otote Miser Auto Createk Standard Correction All Auto.

I took a continuous shooting of the seagull flying in the distance.The subject was small, but he followed me.Used lens FE 70-200mm F2.8 GM II, aperture F2.8, shutter speed 1/2000 seconds, ISO100, White Balance Auto, D Range Otote Miser Auto Create, Creatok Standard Correction All Auto.

A part of the above photo was trimmed with a full HD equivalent (long side 1980 pixels).I was surprised that it was in focus.

 The highest sensitivity is the same as the regular ISO51200 and the extended ISO202800.Until ISO6400, noise and resolution feel less noticeable and does not make you feel high sensitivity.

 After exceeding ISO12800, the image quality gradually deteriorates, but if it is expanded and does not look at the details, it can be accepted with extended ISO102400.Even if the number of pixels is improved, the high -sensitivity image quality is excellent.
