    The imaging capability of the high-resolution 4K lens
 
We compared the brightness profiles of white and black. (Red circles indicate the positions of the glass scale)
 
| 
 Conventional Lens 
  
      
  
  
  
The area of blurriness near the border of black and white is wider, and the rise of the brightness profile is gradual.

 High-Resolution 4K Lens 
  
      
  
  
  
The clear area near the border of black and white is wider, and the rise of the brightness profile is sharp.
