Sony has announced the Cyber-shot DSC-WX300, DSC-HX300 and DSC-TX30 compact cameras. The HX300 is a 50x superzoom with a 24-1200mm equivalent lens in front of a 20MP CMOS sensor. Meanwhile the WX300 is a compact superzoom that Sony says is the slimmest 20x camera. It has an 18MP CMOS chip behind its 25-500mm equiv. lens. Finally, the tough, waterproof card-style TX30 shares the same sensor and offers a 26-130mm equiv zoom.
