Thanks a lot to William, thanks to his questions, I found a solution to increase the rendering quality and clarity using Pathtracing.
Standart Settings. Focus 20. 2:1 Sensor Width and Height .
Result. Blured image.
New solution. Focus 40 or 1:1 Sensor Width and Height + Add Layer Camera + Overscan Percentage 1.
Result.
Don’t forget that the rendering time will be increased, so it’s not necessary to use huge samples values.
We can say that these settings replace Screen Percentage, which makes the pixel density larger.
