Lens Detail

This is an optical zoom-in of the area in the scene outlighed in RED. This represents the higher clarity seen by the lens even though neither the eye nor the camera image sensor can see as much detail.

Caveat

This is actualy from a second photo, take much closer to the subject, which simply allows showing the detail the camera optics might achieve in the light getting to the sensor. Obviously, the camera sensor cannot image this much detail.
