2. Cameras that don't need focusing

Capturing an image without focusing sounds interesting; Lytro has done it in reality. The Lytro camera allows changing the focus of an image after capturing. The camera has a light field sensor that collects the color, intensity, and the direction of every light ray flowing into the camera and captures a picture in four dimensions which helps to refocus after capturing.

Some smartphone manufactures are already trying to introduce this technology for their forthcoming mobile devices. So you can look forward to click without focusing.
