Samsung has launched its latest invention, the Galaxy S9, with a similar all-screen design of the popular Galaxy s8 but its re-invented camera system is a game-changer.
The Galaxy S9 will have
a 5.8in screen, while the larger S9+ will have a 6.2in screen. Both 8.5mm thick smart phones have curved screens, thin bezels, stereo speakers and reduced top and bottom non-screen elements compared to last year’s models. This year the S9+ will come with more memory and storage compared to the smaller S9, and will also have a dual-camera system similar to that fitted to Samsung’s larger Note 8, which includes a telephoto camera. But it is the wide-angle camera fitted to both models that marks the biggest change for the smart phone. The 12-megapixel camera has the first variable aperture fitted to a smart phone, which physically switches between an f-stop of 1.5 for low-light photography and an f-stop of 2.4 for shooting outdoors.
“We were looking at how we can copy what the human eye can do automatically,” said Maxime Guirauton, marketing director for Samsung.

Guirauton said that the dual-aperture system provided the best of both worlds, allowing the camera to let in as much light as possible for shooting in dark environments, and providing a shallow depth of field for the pleasing bokeh effects often created artificially with software, while also making sure outdoor photography in good light doesn’t suffer.


The new camera also has a new super slow-motion ability, capable of shooting at an incredible 960 frames per second, turning a 0.2 second event into six seconds of normal film. Its rivals such as Apple’s iPhone X and Google Pixel 2 shoot at a maximum of 240 frames per second.
