Collapsible lens patent

The japanese blog Egami (Click here) found a new Sony patent disclosing a collapsible lens technology. The image on top shows the lens in full retracted position. The single lenses are in contact with the other lenses to minimize the length. Actually only Olympus is offering such a lens (The 14-42mm kit lens). Collapsible lenses and in future also the liquid lens technology should allow Sony to create very small lenses. Can’t wait to see one of these lenses for real!
