Lenses and cameras

A somewhat old article which I missed, found at the OISBlog, on electrically tunable lenses.
As the predominant method of focusing images for over a century, mechanical lens motion sharply contradicts the biological methods found in nature. By leveraging principles based on these methods, manufacturers are now developing different types of small deformable lenses that can be tuned over various focal distances. Because these lens systems can be miniaturized relatively easily, they are finding applications in smart machine-vision cameras, endoscopy systems, and cell phones.
And a review of the Canon Expo 2010, with references to both their full wafer, 600 micron pixel and their 120Mpixel detectors. Cool stuff.
