ELI5: Why is it so hard for a camera lens to capture the depth and the quality as seen with a naked eye?
gpt
The simple answer is that it is just as hard for the eye. 

Our eyes also have depth of field issues, but we constantly shift the point of focus. Rather than thinking if the eye as taking a photo think of it more like a video camera that can refocus almost instantly. As soon as we look at a blurry part of the picture it immediately snaps into focus. 

Our brain then stitches it all together so we perceive it as a sharply in focus world.
