Samsung EX1 is amazing, it boasts a 24mm ultra-wide F1.8 lens which is rarely makes its appearance on such kinds of compact camera and it employs a 1/1.7-inch CCD sensor, allowing an ISO up to 3200 at even full resolution, which is nothing to be sneeze at. Another hightlight of the Samsung EX1 is undoubtedly its 3.0-inch OLED screen – the OLED screens can be more efficient and offer greater contrast than LCD panels.
