After months of speculation and leaks, Samsung has finally unveiled its Galaxy S9 and Galaxy S9 Plus flagships at Mobile World Congress 2018, which kicked off in Barcelona on February 26th. We already knew that the new phones would be similar to their predecessors in terms of design, and now this has been confirmed at the official presentation. However, Samsung also said that the infinity displays of the new flagships have been improved with the expectation of an audience that spends a lot of time on social networks.
The screens of the Galaxy S9 and Galaxy S9 Plus models received the same aspect ratio (18.5:9), curved edges and bright Super AMOLED panels. Both new items differ only in diagonals: 5.8 inches for the Galaxy S9 and 6.2 inches for the Galaxy S9 Plus.
But most of all at the exhibition, everyone was interested in only one question: what new things did the engineers bring to the performance of built-in cameras? Recall that in its announcements before the full release, Samsung talked about the so-called reimagined cameras (translated from English – “rethought”), which suggested a complete reworking of the camera modules.
The Samsung Galaxy S9 received a main camera with a single lens, but the Galaxy S9 Plus boasts a dual matrix. Representatives of the company at the same time said that the cameras installed in the Galaxy S9 and Galaxy S9 Plus are by far the most innovative, and their performance is dictated by the structure of the human eye. In particular, we are talking about a wide-angle lens with a 12 megapixel matrix, which is installed in both models. In addition, all leading lenses use an optical stabilization system.
One of the key features of the camera module is the ability to automatically switch between f/1.5 and f/2.4 apertures according to lighting conditions. Remember, the Galaxy S8 had a maximum aperture of f/1.7. The local large aperture, according to the manufacturer, allows the camera to capture 28% more light and get detailed pictures with minimal noise even in dark rooms. The only pity is that in manual mode, the user cannot choose an average aperture value between f / 1.5 and f / 2.4.
A similar technology with the ability to switch between aperture values was implemented in the Samsung W2018 smartphone. But this elite model is unrealistically expensive (about 95,000 rubles), so, unlike the Galaxy S9 and Galaxy S9 Plus, it will not become mass.
The second camera of the Galaxy S9 Plus, which acts as an auxiliary camera, is equipped with a 2x optical zoom telephoto lens, has a resolution of 12 megapixels, but does not have a variable aperture. The aperture value is f/2.4. With it, you can create the background blur or “bokeh” effect beloved by many photographers.
In terms of selfie cameras, both smartphones received an equivalent 8-megapixel sensor with f / 1.7 aperture and autofocus, similar to previous flagships. So in terms of “selfies” there are no special improvers.
To create movies, you can use the slow-motion mode at 960 frames per second at HD (720p) resolution. We have already seen a similar mode in the Sony Xperia XZs, which was shown as part of last year’s MWC 2017.
As for Samsung devices, in slow-mo mode (at 960 fps), users can record 0.2 second segments of time, making them part of long clips. There is even an “auto-capture” option for this, which, when recording a video, can automatically turn on the slow motion mode by detecting movement in the frame. These features are available on both models of Samsung’s flagship devices.
