This time, collaboration with the popular Korean group "BTS"
The Galaxy S21 series has three models, S21+ 5G, which enhances the display, and S21 Ultra 5g, which enhances the camera function in addition to the unmarked S21 5G.Of these, the S21 is a somewhat irregular sales from NTT DOCOMO and au, S21+from au, and S21 ULTRA is from DOCOMO.
The back, which has renewed the design and adopted matte glass material, has no flashy reflection and has a good touch.In particular, the Violet color of S21 is a little color that you want a little, and it is a shame that it is not prepared by S21+and S21 Ultra.
The S21 color is phantom violet, phantom gray, phantom white, and the S21+color is two colors: phantom silver, phantom black, and S21 ULTRA is phantom black and phantom silver.
The renewed design is compiled by consolidating the camera part in the upper left, giving a sense of unity of color with the side.Although the camera lined up vertically is large, it has a small protrusion and has a sophisticated design as a design accent.
However, the S21 Ultra has a considerably stronger camera presence.The protrusion is also intense and impactful.If you want a compact size, the unique S21 looks good.The S21+released by au is characterized by a larger screen than S21.
The screen size is 6.2 inch FHD+(2,400 x 1,080 dots) for the S21, while the S21+is a 6.7 -inch FHD+(2,400 x 1,080 dots), and the S21+has a good balance between the large screen and the body size.。If you look badly, it's not halfway.
The top S21 Ultra is a heavyweight class.Although the screen size is 6.8 inches, there is not much difference from S21+, but the screen resolution of S21 Ultra is QUAD HD+(3,200 x 2,400 dots) and high resolution.The weight is about 200g of S21+, and the S21 Ultra is obviously heavy.However, the balance is not so bad, and the weight is not biased to the upper part of the camera.As a matter of fact, the width is 76mm as S21+, so the ease of holding does not change much.
Taking advantage of the large screen, S21 ULTRA is the first S series to support S Pen (sold separately).Handwriting input has become more comfortable by supporting the dedicated pen used in the company's NOTE series and tablets.However, unlike the note series, the S pen cannot be inserted into the main unit, and it is not compatible with the function of connecting with Bluetooth and operating the main unit with a pen.S -pen can be purchased individually, and S -pen -mounted cases will be sold.
The S21 Ultra camera is equipped with a 18 billion pixel sensor as the main camera, appropriate for the "Ultra" line.By treating nine pixels as one pixel by pixel vinning (simply improving the performance that collects light), the image quality is improved.
Furthermore, the four more cameras cover the four focus distance: ultra -wide -angle, wide -angle (main), tripled telephoto camera, and 10 times the telephoto camera.It is a great strength to be able to cover the magnification of 10 times with an optical lens.In addition, digital zoom supports up to 100 times.The image quality deteriorates considerably, but depending on the scene, it is easy to use excellent shooting.To be precise, there is another TOF camera for deep positioning.
For details on the camera, please read the global version of "GALAXY S21 ULTRA" reviews, 18 billion pixel cameras and optical 3 times or 10 times lenses ".
S21 and S21+, on the other hand, are triple cameras with ultra -wide -angle, wide -angle (main), and triple telephoto.A telephoto camera adopts a 64 million pixel high -pixel sensor.This was the same in the previous S20 series, but the actual focal length of the telephoto camera is short (wide angle of angle), but the focal length is three times equivalent by using digital zoom.By the way, S20+was equipped with a TOF camera for deep positioning, but was omitted in S21+.
The video shooting function is equivalent to the three models of S21, S21+and S21 Ultra.It also supports 8K / 24fps shooting and 4K / 60fps shooting.With "Single Takes", which records multiple angles of angle of views and videos and photos in one shot, "Director's View", which allows you to record a video and take a video by switching the focal length with one touch.Equipped with a certain function.
As a function that utilizes the camera, I focused on the "AI eraser" function.If you touch the object of the shot image, it will automatically select and delete it.Although it is a function like Photoshop's "paint according to the content", it is not perfect, such as the fact that the selection of the object is automatic and the crushing around the object is filled with a certain background, so it can not be erased neatly unless it is a constant background.There is no doubt that it is still useful.
[Video] An example of AI eraser.It will erase it beautifully just by touching the object.It seems to work if the background is uniform like this
If the background is uniform, the AI will automatically determine the object, so it seems to be usable in various scenes.
All three models of S21, S21+and S21 ULTRA are not overlooked as a domestic model.In addition, it is a single SIM as a domestic version, and it is optimized for the frequency band of each carrier.S21 and S21+also support 5G SUB6, S21 Ultra also supports millimeters.
S21, which has a compact and necessary function, can be purchased in DoCoMo and au.If you want a large screen for au users, you will choose S21+, and in the case of docomo, you will choose S21 Ultra.If you do not need an S pen or camera, docomo users can only choose S21 Ultra, and au users who want such functions can only choose S21+.
Recently, MNP has become easier, so it is ant to change your career for the model you want.Personally, I want S21 Ultra, so if you buy it, it will be a docomo.
