PENTAX K-5 incorporates a new generation CMOS sensor, combined with the reliable PRIME II Imaging Engine, which produce high-resolution, rich-gradation digital images. The K-5 also offers a wide sensitivity range, from ISO 100 to 12800, which can be expanded to ISO 80~51200. As the analogue/Digital conversion is done within the sensor, K-5 features an impressive noise management.
