You may know from our past posts on 43rumors that one of the future key technologies will be the “liquid lens”. This allows lenses to be super compact, super fast AF with zero noise and other great features. My friend Frank from CanonWatch (Click here) found that cool video you see on top of this post. It explains well how the principle works. If you don’t have time to watch it all go on minute 7:40 of the video. I bet that after seeing this you will run to your tap to test that for yourself :)
