The Sony Cyber-shot DSC-TX1 is amongst the first Cyber-shots to use one of Sony's new back illuminated CMOS sensors. According to Sony, its 'Exmor R' sensor offers low-light performance with approximately twice the sensitivity of traditional image sensors. The sensor has been incorporated into familiar W and T series bodies. The TX1 is a touch screen camera with 4x zoom lens (35-140mm equiv.).
