The lens was free of dust and fingerprints.  Preceding and following images did not show the anomolies.  The images have been examined by three Photoshop experts running various filters and were unable to refine any further details.  Two highly qualified photographers (photo analysts) were asked to examine the photos with no explaination.

Although the anomolies look like fingerprints on the lens, the ribbing effect reminds me of the Lockheed-Martin "Stealth Blimp" and in one image the "ribbing" appears reversed.  I remind the reader that the human eye cannot see into infrared and ultraviolet wavelengths and that most digital cameras can capture at least infrared.  Further, meta-materials have been in the news showing their ability to visually hide objects.  Plasma and other energy fields are being researched for potential use as energy fields to block radiations and physical matter from entering.  Given the length of time internet information has been available to the public it is highly likely that incredible advances in these areas have been made in our classified arenas.
