What is optical hybrid zoom for mobile phones?

The pain point of most mobile phone photography is that it is equipped with digital zoom instead of optical zoom. Digital zoom is just a zoom operation, that is, part of the existing photo is enlarged or reduced to the size that the user wants, but the sharpness is greatly lost after enlargement.

Optical zoom relies on the refraction of light without losing the image quality, and can shoot small objects in the distance as clearly as those near, which is also a widely used technology in SLR and digital cameras.

In order to improve the camera level of mobile phone, there is no way to break through the optical and physical limitations, and we can only work hard on the number and pixel function of mobile phone cameras. From single camera to double camera to triple camera, different cameras realize different functions. Ultra-wide-angle lens has a wide angle of view and a large depth of field, which has favorable conditions for expressing open space and grand scenes. Ultra-high definition lens can clearly present distant objects in the lens by adding pixels, which must be very needed by the audience in the back row of ball games and concerts. Ultra-telephoto lens is suitable for shooting distant scenes and details of inaccessible objects (such as the roof of high-rise buildings), and the shooting effect is better when ultra-high definition lens and ultra-telephoto lens are used together.

At present, Huawei P30PRO and OPPO Reno are the best mobile phones with extremely high optical hybrid zoom.
