It is clear that manufacturers know that the user, when purchasing a mobile phone, is very aware of the photographic section. And that is why its engineers and developers put all the meat on the grill to surprise the potential buyer day by day. Nothing ago, from the hand of the manufacturer Xiaomi, we learned that, shortly, they would launch the first mobile with a sensor of no less than 108 megapixels. Now we have news about the advance in telephoto lens, as an 8x optical zoom is in development.
The current trend in the photographic section is to integrate two or more lenses, since, at the moment, it is impossible to have just one that covers different angles, as happens in professional cameras. Sometimes we can find mobiles with up to four lenses (a basic angle, a wide angle, a telephoto lens and a depth sensor for portrait mode) and it is already difficult to observe mobiles that only have a single main lens, as it is rare to see a terminal with frames on screen.
The company Yaguang Electronics Co., located in Taiwan, wants to begin to achieve that with a single lens we can have several options of optical zoom. Thus, it is developing a module for a single camera with a periscope lens, based on aspherical glass lenses, with which it intends to achieve an optical zoom of between 6 and 8 times in a single lens. This variable zoom lens could be even more powerful than a triple camera setup. This lens, in addition, thanks to the algorithms of the HDR mode and Artificial Intelligence could suppose a substantial improvement in images taken in low light or at night.
Thanks to the variable optical zoom, the triple camera configuration could be eliminated, making it possible for the mid and high range to carry only one, with the consequent reduction in weight on the terminal. This single lens solution is still in the development phase so it could take a long time before mass production. At least a couple of more years we will continue to see phones with two, three and four cameras to be able to play with different angles.
