There is a new prototype camera on the market that I would not mind laying my hands on. Apparently, the camera allows a picture’s focus to be adjusted after it is taken: NYT link.
Before I read the NYT article in full, I was skeptical about it, thinking that the focus adjustment will be a photo post-processing trick. But it seems that it's not the case, and that the camera has a special sensor "microlens array", which captures more light data from many more angles than a conventional camera.
It will be interesting to see how this camera performs in real life and if it will indeed be the next breakthrough in digital camera technology.
