剛剛逛 SonyAlphaRumors 網站發現一個大革命，不得不分享給各位喜愛 Sony 的攝友：
This is a first: Brand new Sony patent discloses an “electric zoom lens” design
http://www.sonyalpharumors.com/first-brand-new-sony-patent-discloses-electric-lens-design/It describes a zoom lens having normal optical elements and in the center two liquid crystal lenses. The liquid crystal lenses can change the “refractive index” with the use of electric signal.
it is conceivable to use what is called a liquid crystal lens, in which liquid crystal is disposed between two planar lens substrates. This is because by applying an electrical signal to the liquid crystal to vary the refractive index of the liquid crystal, it becomes possible to vary the focal length of the lens without moving the lens itself.
In theory by using liquid crystal elements you can make smaller and superfast autofocus lenses. Because you no longer need to move around lenses on a great distance to focus or zoom in and out.
這個是繼兩年前 Sony 發表曲面CMOS專利以來最令我興奮的新發明，來看當時的新聞：

Sony 真的很用心在創新研發光學科技，帶領全世界不斷的進步與革命！
所以我覺得不只美國51區有外星人在幫忙，Sony 總部應該也有！
