Greeting MIUIers!


Love to capture long range picture with your beloved smartphones? Zooming is the solution! We all know that there are two ways to zoom in the picture which is optical zoom or digital zoom. So which one do you prefer? Optical zoom or digital zoom?

Optical Zoom Vs Digital Zoom

What is Digital Zoom?
Digital zoom is a not a true zoom that decreasing the apparent angle of view by taking the central portion and enlarge it. In short, the camera crops a part of the image and then enlarges it back to size. Hence, image quality will lost and the image is distorted. If you commonly using digital zoom with your phone and wondered why your pictures tend to distorted, now you know why. Majority, smartphone has inbuilt digital zoom up to 10x.

  

What is Optical Zoom?
Optical zoom is the actual zoom by using physical lenses such as telephoto lens. It manipulate the focal length of a camera by adjusting the physical zoom lens. In this case, the image quality will be conserved in while zooming. However, mostly Optical zoom are only available in dual cameras phone such as Mi 6, One Plus 5, iPhone 7 Plus, Mi 5x and many more. Hope to see more optical zoom Implemented in future smartphones.

Optical Zoom and Digital Zoom Pros and Cons

Digital Zoom advantages
  • 1. Widely used in most smartphone
  • 2. You don't need a computer to crop the picture.
  • 3. Suitable for those 'Click and Go' who like to capture zoom photos without concerning the image quality

Digital zoom disadvantages
  • 1. Image quality will lost
  • 2. Usually after 2x digital zoom, the image is started to be distorted.

Optical zoom advantages
  • 1. Image quality is conserved
  • 2. Image will less likely distorted and noisy after 4x zooming
  • 3. Ideal for professional photographer who like to capture long range photo

Optical zoom disadvantages
  • 1. Not widely used in Market, only a few devices with dual camera has optical zoom.

What's Your Choice?

The great advantage of Optical Zoom is you can zoom with less image quality lost, but it is not much seen in current smartphones, on the other hand, digital zoom is widely used in smartphones, it is good for those who just wanted to simply capture photo. Considering the factors, what would be your choice?

Which One Do You Prefer? Optical Zoom or Digital Zoom?

UncleKodjo I will stand with Optical Zoom, which uses lenses for zooming as against Digital Zoom, which is just a an enlargement of the current image and would lead to loss of quality.  15:14, Sep-15-2017
