As if the camera on the phone has nothing to upgrade, but the appearance of the Galaxy S9 and aperture change lens system continues to make users feel more exciting than ever. Instead of just increasing the size or improving the quality of the sensor, Samsung has chosen a completely new way to create a more complete camera experience: allowing the lens to change from f / 1.5 to f / 2.4.
What is the change of aperture? How does it work?
For a normal person this is quite hard to understand. To put it simply, reducing the aperture to f / 2.4 is like putting on sunglasses to see better when it’s hot.
The difference between the three aperture f / 1.5, f / 2 and f / 2.4. The bigger the sensor, the more light it gets, but the more likely it is to have a chromatic aberration.
The weakness of the large aperture lenses (such as f / 1.5 on the Galaxy S9) is that the ability to shoot in low light conditions is slightly reduced. Images will now experience phenomena such as aberration, reducing the sharpness of the details, especially around the border. When the aperture is reduced to f / 2.4, the image will look sharper, less blurry , especially when shooting from a distance.
Why not reduce the aperture directly to f / 2.4 but have to change the aperture? Of course, to preserve the ability to capture low light. The larger the aperture, the better the sensor, the better the night vision, the better and the less noise . This is always true, as the Galaxy S8, Note8 (f / 1.7) always shines brighter, sharper than other devices in low light conditions.
Aperture f / 1.5 allows the Galaxy S9 (left) to shoot brighter than the iPhone X (right).
In addition, a large aperture means better font removal . Close-up pictures will become more prominent with the subject being separated from the background.
By combining the two aperture sizes, we have the advantage of capturing both bright and light images. The Galaxy S9 shooting experience is now becoming more professional, coming closer to the limit of DSLR cameras in the market.
Photos taken from the Galaxy S9 in sufficient condition at a f / 2.4 aperture (left) is clearly better than f / 1.5 (right).
Is it the necessary move of the mobile village?
Although not much attention, but there are many experts and writers of technology sites around the world are convinced that this feature will definitely become the new standard in the smartphone village in the future.
Is this the future of mobile photography?
While smartphones are at the top of things in most respects, these “small but powerful” upgrades will be the key to “perfecting” the photography experience.
It will not be long before other manufacturers follow this trend. And maybe in just a few years, Samsung will continue to launch a new generation of smartphones with more revolutionary changes. Let’s wait for the answer.
