Photokina 2012: Canon has refreshed its G-series enthusiast compact with the G15, and created the implausible SX50 HS. The G15 is a successor to the G12 and is built around a 12MP, 1/1.7" CMOS sensor. Its lens also gets an upgrade - retaining its 28-140mm range but now with a maximum aperture of F1.8-2.8. It loses the G12's articulated screen but gains a higher-resolution, 920k dot panel. Meanwhile the SX50 HS features a remarkable 24-1200mm equivalent 50x zoom, thanks to its smaller 1/2.3" CMOS sensor.
