As seen with most high-end smartphones and even those with a small budget, the next zoom is optical zoom. In a digital camera you have probably seen the lens barrel bend and rotate and move forward when you increase or decrease the magnification View or area of lens . This is because the lens has multiple glass elements, which move you back and forth to expand your subject or higher or lower. This is the true form of optical zoom you can get.

 The optical zoom is  widely used today; It's just that instead of being a complex moving lens system, it's our second sensor with a long focal length for a 'zoom-in' perspective. When you tap the 2x or 3x button in your Camera My app, the phone only switches to the zoom or telephoto sensor, if your smartphone supports it. This type of zoom usually provides the best image quality.

This type of zoom, which is quickly adopted by many smartphone manufacturers, enhances images captured by telephoto cameras using AI or computational photography methods to fill in missing details of textures and colors. To enhance some details, it also attaches image data from other sensors. This method is currently the best way to get high quality zoom, while still maintaining very good image quality.





Digital zoom is a method of reducing the exact angle of view of a digital photograph or video image. It is accomplished by cutting an image into a field with the same aspect ratio as the original and by scaling to the original dimensions of the image. My camera optics are not adjusted. It is accomplished electronically, so no optical resolution is obtained.

In weakly compressed cameras, digital zoom is preferred in post-processing, as zoom can be applied before the details are lost in compression. In a camera that saves in a lossless format, the results of resizing in post-production are comparable to or greater than digital zoom.

Lower-end camera phones use only digital zoom and do not have optical zoom, while many high-end phones have additional rear cameras, including a fixed telephoto lens, which allows to simulate optical zoom option.
