The Pentax K7 is smaller and lighter than its predecessor and is geared up for extreme conditions thanks to its magnesium alloy body with 77 weather-proof joints. The K-7 has a 14.6-megapixel CMOS sensor and uses Prime II image processing technology to reduce digital noise and enhance exposure. The sensor is also magnetically stabilised to reduce photographic reduction and keep blurring to a minimum no matter what type of 35mm or digital lens you're using.
