The most noticeable feature of the Samsung HMX-U20 is the lens, which makes it look more like a serious piece of photographic equipment than a pocket video camera. However, this feature has real benefits, like optical zoom, that differentiate the U20 from its brethren and their digital zooms. The effect is quick, smooth zooming that can be accessed during full 1080p recording and doesn’t produce noise or distortion.
