German research team has designed the first liquid camera lens which has no moving parts for switching between two levels of magnification. Samsung has used this technology in some of their camera cell phone models due to its small size factor and low cost of manufacturing. However professional cameras which had bulky zoom lens will get more benefit from this technology as altering the focus of these liquid lens gives the same zoom function which requires several traditional lenses to achieve. Since glass lens used today have fixed focus length, so for the zoom function two or more lenses coupled with some mechanical parts to move lens for adjustment which surely made the device bulky.
