Galaxy S20 series,Globally, three models of S20, S20+, S20 UltraWas prepared. In Japan, NTT Docomo and au released the S20 and S20+, but the S20 Ultra was abandoned. Personally, I was disappointed that the top model did not appear in Japan.
However,au introduces "Galaxy S20 Ultra"It was decided to do. Here, we will verify the ability centering on the Galaxy S20 series top model.
Big and heavy, but the top of the Galaxy S20 series "Galaxy S20 Ultra"
As mentioned above, two models of the Galaxy S20 series have appeared in Japan from two companies, Docomo and au. The specifications are of course the same, but there are some differences in color. S20 5G [SC-51A for Docomo, SCG01 for au] comes in three colors: Cosmic Gray, Cloud White, and Cloud Blue. For S20+ 5G, the Docomo version SC-52A is Cosmic Gray, and the au version SCG02 is Cosmic Gray and Cloud Blue.
The SCG03 is added to the au lineup as the Galaxy S20 Ultra 5G. au is a foldable smartphoneGalaxy Z FlipWe are focusing on Galaxy, such as the only one in Japan. This S20 Ultra is also the only model in Japan.
The Z Flip released in Japan is almost a global version, so there is no au logo on the back side or it is not compatible with Osaifu-Keitai. The S20 Ultra has the same form this time, but in any case, the situation where the top model of the Galaxy S20 series was not released in Japan was avoided.
Well, first let's compare the specifications of each.
Except for the camera, the basic specifications are the same. The big difference is the screen size, which is larger with S20, S20+, S20 Ultra and the battery capacity increases. In particular, the S20 Ultra is one size larger than the S20+ and has a heavy body weighing over 200g.
Since the S20 Ultra is large, it has a display size of 6.9 inches and a battery capacity of 5,000 mAh with a large screen and long life. Size and weight are also trade-offs. It will be different depending on the user.
Another difference is that the S20 supports 5G communication only on Sub6, and the S20+ and S20 Ultra support millimeter waves in addition to Sub6.
In terms of performance, all three models use the same SoC, so basically they can be considered equivalent. Therefore, it seems to be good to choose by size. In fact, the S20 Ultra is a little too big for an adult man like me. There is also a situation where it is difficult to operate with one hand because it is heavy. Personally, I often wear a case, attach a strap and hang it around my neck, but if it exceeds 200 g, it will feel tight on my neck.
On the other hand, when it comes to viewing content, the S20 Ultra's large screen is immediately advantageous. Although the numbers are small, the larger the screen, the better the visibility of the screen. The larger the screen, the better for still images and videos.
Whether you're browsing a website with a browser or viewing texts, videos, and photos on SNS, the screen size is advantageous. The Galaxy S20 series has the function of changing the refresh rate from the conventional 60Hz to 120Hz, realizing smooth video playback and scrolling. However, if you set the display to the highest resolution WQHD+ [3,200 x 1,440 dots], the refresh rate will stop at 60 Hz, which is a little disappointing.
If you choose here
Therefore, the choice depends on the size and weight, or which one is more important. If you are a "high end anyway", Galaxy S20 Ultra is the rule. Do not consider size, weight or price. It also supports millimeter waves, making it perfect for future high-speed networks. Of course, if I also choose, it will be S20 Ultra.
If you want a high-performance, high-performance camera, then the S20. S20 is also a high-end terminal with a bulk price of over 100,000 yen [excluding various discounts]. It's relatively compact and light, so you can carry it around easily. Although it does not support 5G millimeter waves, it is not so problematic for the time being because the environment where you can experience millimeter waves is limited.
The S20+ is in a rather halfway position. Unlike the S20 in that it has a depth positioning camera, the display size is also larger than the S20 and supports millimeter waves, but these can all be covered by the S20 Ultra. If it's difficult to choose the S20 Ultra, then it will be the S20+. For DoCoMo users who do not have S20 Ultra in their lineup, it is a pity that S20 or S20+ is an alternative.
The camera function that can be called the biggest difference
The S20 Series 3 model has some differences, but the biggest difference is still the camera. The S20 Ultra has an ultra-high pixel sensor [made by Samsung] of 108 million pixels. Previously used by the Xiaomi, the S20 Ultra now has this as well, allowing you to take high-resolution photos.
As far as the lens specifications and sensor size are concerned, the high pixel count of 108 million pixels seems to be excessive. However, by handling nine pixels as one pixel and increasing the pixel size to 2.4 μm by nanobining technology, various advantages can be obtained. Since a lot of light can be captured when shooting with 12 million pixels, low noise is achieved and the dynamic range is wide, for example, when shooting in dark places.
In contrast, the S20 and S20+ are regular 12-megapixel sensors. Although it is a reasonable design, you cannot use the characteristic functions that take advantage of the high pixels like the S20 Ultra. The basic camera functions including the single take function [*] are the same for all three models. Therefore, the high pixel count is a big difference between the S20 Ultra and the other two models.
As for the camera, S20 is triple, S20+ and S20 Ultra are quad, but since it is triple + depth positioning, there is not much difference in the camera itself used for actual shooting. There are three cameras, wide-angle, ultra-wide-angle, and telephoto, but the angles of view are slightly different.
With all three models, the focal length of the ultra wide-angle camera is 13mm [hereafter, when converted to 35mm format] and the main is 26mm.
The telephoto is 29mm for S20 and S20+ and 103mm for S20 Ultra. On the UI of the camera, S20 and S20+ are 0.5x, 1x, and 3x, and S20 Ultra is 0.5x, 1x, and 5x.
The strange thing is that the actual focal length on the telephoto side and the magnification on the UI do not match. Originally, it was necessary to mount a 78mm lens, which is 3 times that of 26mm, and a 130mm lens, which is also 5 times, but that is not the case. The reason seems to be that the crop using high pixels realizes a telephoto lens.
When switching to the S20 and S20+ 64 million pixel [telephoto] shooting mode, the angle of view is slightly narrower than the main camera, so you can see that it has switched to a 29mm telephoto camera and is in high pixel shooting mode. I will. At this time, you cannot zoom or switch cameras. This may be because cropping cannot be done in the mode that uses all 64 million pixels.
For the S20 Ultra, the telephoto camera has 48 million pixels. The optical magnification is 4 times, but it is 5 times on the UI, and it seems that it is equivalent to 130 mm with digital zoom.
The S20 Ultra also features a high-magnification digital zoom that uses 108 million pixels. The S20 and S20+ have up to 30x digital zoom, while the S20 Ultra has up to 100x digital zoom. It is a very high magnification, equivalent to 2,600 mm when converted to 35 mm.
Of course, the image quality will deteriorate accordingly, so it is not a level that can be used normally. Moreover, if you hold it, the subject will disappear from the screen in a moment with a slight shake. Shooting is difficult, but 100x is a slightly surprising zoom experience.
You can choose the maximum zoom with the feeling that you can't read people's faces and characters, but you can distinguish the shape of things, but the high-magnification digital zoom is still useful. If you zoom up to 30x, the image quality of the S20 Ultra seems to be slightly less than that of the S20 or S20+, probably because the S20 Ultra has more room.
One of the merits of the S20 Ultra's 108-megapixel camera is that you can get a certain resolution even if you enlarge and save a part of the image after shooting. It's like taking a digital zoom after shooting, but if you zoom in on the S20 Ultra gallery app, you can zoom in up to 50x. Of course, the image quality will be reasonable, but it's also fun to refocus on the subject that you didn't notice during shooting.
However, if you shoot with 108 million pixels, the image quality will be degraded in terms of detailed depiction, noise, and dynamic range, and the capacity per image will be as large as tens of MB. It also has the disadvantage of lengthening the recording time and squeezing the internal storage area. Switching the resolution at the time of shooting is easy, so I would like to use them depending on such disadvantages.
The major difference between S20 and S20+ and S20 Ultra is the presence or absence of a depth positioning camera [S20 is not installed]. Since the depth positioning camera can measure the distance to the subject, it is possible to apply background blurring effects more accurately.
The S20, which does not have a depth positioning camera, can also perform distance positioning using the parallax of multiple cameras. As far as I tried, it wasn't much different from the S20+ or S20 Ultra. The display says to keep the distance from 1m to 1.5m to the subject, but there is no difference in distance detection for each model. The S20+ and S20 Ultra seem to be more accurate, as there seems to be some differences in the recognition of small details.
Personally, I think that about 3 times is appropriate for the telephoto side, regardless of the super wide angle side. If it is about 2 times, it is enough to move with your foot, and digital zoom is also good. If the focal length is 3 times as an optical lens, it will be difficult to earn with your feet, and it will be easier to use.
And the S20 Ultra is 5 times [optically about 4 times]. When it becomes 5 times, the scene "too close" will appear next time, so there will be scenes where you can think about how to use it. However, it has a UI that allows you to easily set 2x or 4x focal length by using the digital zoom that uses 108 million pixels, so if you also use that UI, you can perform flexible zoom operations.
"Galaxy S20" for cospa, "Galaxy S20 Ultra" for high-end orientation and camera focus
The camera of the S20 Ultran is attractive for its new features that combine a high pixel sensor. If you shoot 108 million pixels in 12 million pixel mode, the sharpness will be slightly stronger, but the overall picture will be clear and you can take stable pictures in any scene. Pixel composition technology such as nano binning has the effect of dynamic range and noise reduction, and the image quality will be the best in the industry.
High-power zoom by digital processing is a little unreasonable, but it seems that not only distant shooting but also astronomical shooting like the moon [unfortunately this time I could not shoot due to the weather].
S20 is the best in terms of cost performance. The ability of the camera is the same as that of S20+, there is no particular difference in image quality, and it seems that there is no big difference between S20 and S20+ with or without the depth positioning camera. Given that 5G millimeter waves are not needed for the time being, the S20 is fine.
In contrast, the S20 Ultra is quite special. It is a high-end camera with a high degree of originality and a large screen. Millimeter wave is also supported and there is no problem in future. Some people may think that the lack of the au logo is a merit, and it may be a minus for those who do not support Osaifu-Keitai. However, it is very attractive when viewed as an "ultra-high-speed network-compatible camera capable of ultra-high-magnification photography," so it may be an option for those who value such points.
