Cheap and small wide-angle lens takes the fish out of "fisheye"
The main problem with bog standard wide-angle lenses is their inherent tendency to distort images, this distortion creates obvious problems for remote operators of robots and camera surveillance of large rooms, for instance. A team of South Koreans, however, are claiming to have improved on bulky and expensive "rectilinear" lenses -- which offer up a low-distortion, wide-angle view -- by developing a lens that offers this clear view as well as being cheap, light, and small. That makes it far more suitable for use in monitoring devices with strict weight / size constraints, such as the aforementioned robots. At around $100, the price should also give security teams little excuse to not upgrade their gear by screwing one of these onto existing bullet cameras.
