The Pentax K-3 is an APS-C DSLR designed for experienced photographers and loaded with features. With a 24 megapixel image sensor, brand new PRIME III imaging engine, and SAFOX11 auto focus engine the K-3 is designed for pro level performance. Not only this, but the K-3 can take its capabilities anywhere thanks to a weather and cold proof magnesium alloy body.
The shutter, diaphragm and mirror are independently regulated, helping to provide a high speed 8.3 frame-per-second burst rate and 1/8000 maximum shutter speed. The Pentax K-3 is the first camera to offer a Selectable Anti-Aliasing filter, which replaces the physical filter with a sensor-based anti-aliasing simulator. This increases the effective light sensitivity of the APS-C CMOS image sensor.
