The Panasonic LUMIX G Micro System Camera GX1 is Superb Image Quality and Performance Combined with a Premium Design. The 16.0-megapixel Live MOS sensor plays a big role in high quality image rendering. With the dedicated circuit which reads out signals with minimum noise, the level of noise is significantly suppressed by more than 66%. Notably max ISO 12800 is available with DMC-GX1. In shooting at high ISO setting, S/N value is improved by approx. 200% compared with the conventional 12.1-megapixel sensor. The sensor performance improves by 6db at ISO 3200 and max. 9db at ISO 6400, resulting in the dramatically flawless picture without noise.
