Xiaomi invents the optimal large aperture zoom for mobile phones

Mobile phones will become compact cameras

Although we have already seen cell phones with varifocal lenses Previously, and today the periscope lenses offer up to 10 optical magnifications, Xiaomi’s proposal goes far beyond what one might think at first glance, since the secret of this optical zoom system would be in the lens aperture. .

According to the manufacturer, it was shown through his official profile in Weibo, the lens would include a large aperture that would allow more than 300% more light in than current systems and would also have a stabilization system that would help prevent vibrations.

The brand has posted a video to demonstrate how the lens moves during operation, and also showed a focus adjustment demonstration where you can see that the depth of field is quite remarkable at short distances between objects and background.

There is still a lot to do

Considering what we have seen, it is clear that aesthetically this is still a first functional prototype, so the system may still have a lot to develop, but it is still a very interesting advancement that could change the current perspective of current camera systems on mobile phones. .

Fewer cameras in the future

And that’s what most (if not all) phones today have more than two cameras, This system would help reduce the number of lenses by being able to have different focal lengths in the same lens, at the same time it would enjoy a generous aperture with which to capture as much light as possible.

That said, if today we find a main sensor of many megapixels with a wide angle lens and a second sensor of less megapixels with a magnifying lens, this new system would allow to use the same sensor to take both an angular photo and a zoom photo.

Why are zoom lenses not used as the main camera today? Well, basically because of the opening problem. The main sensors, having a more angular lens, have a larger aperture with which to capture much more light than sensors with magnifying glasses, so Xiaomi’s idea would finally solve this impediment, hence the two merged cameras. in one with the idea of ​​reducing cameras on the back of phones. Not bad, right?
