Sony has announced the Cyber-shot DSC-WX1 and DSC-TX1 digital compacts, the first to use 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 WX1 features a 5x zoom starting at 24mm equivalent and f/2.4. The TX1 is a touch screen camera with 4x zoom lens (35-140mm equiv.). Like the existing, conventional CMOS-based HX1, both cameras offer HD video recording and a Sweep Panorama mode.
