Even with a modern smart phone you can take pictures in different distances and then use software to get an overall picture. It seems they are very proud of this progress, so I doubt you can do something similar wir just on lens. | |

Referring to the paper I linked again, the authors pass the parallel light rays through a volume of water of length more than 20 cm, and are able to get sharp images of anything in that volume. Granted, their 85 mm Nikon lens probably has an aperture that can be set to a small opening, and I couldn't find any information about that setting in the paper. | |
