The K-3 is a Pentax high-resolution APS-C camera designed for semi-pro and professional photographers. Key features include:

24MP APS-C CMOS Sensor. This high-res sensor provides extremely high image quality at a wide range of sensitivities. It’s the first digital camera to offer a user-selectable anti-aliasing filter. Turning this filter off allows increased image sharpness and detail, while turning it on reduces moiré. The updated PRIME III Processor gives you an ISO sensitivity range of 80-51,200 and continuous shooting at up to 8.3 fps.

Improved Autofocus and Metering Systems. The K-3 features a redesigned SAFOX 11 Autofocus Module with an emphasis on low-light performance. It employs 27 focus points (25 of which are cross-type) for improved accuracy, and is rated to work in lighting conditions from -3 to +20 EV. Its metering system now boasts an up to 86,000-pixel RGB sensor, making it a marked improvement over previous generations. This translates to increased exposure accuracy and white balance.

In-Camera Shake Reduction. Provides an estimated 3.5 EV of correction, allowing you to shoot at low shutter speeds.

Full HD Video. The K-3 sees a few notable improvements to video recording. It now shoots 1920 × 1080 video at 60i, 30p, and 24p, and has a dedicated movie button for start/stop recording. There are external mic and headphone inputs for improved audio recording, and the H.264 video format enables easier workflow in popular video-editing software.

High-Quality Build. Build quality is always a key factor in any Pentax DSLR, and the K-3 is no different. The durable magnesium-alloy body with stainless-steel chassis gives the camera a solid feel, while the 92 independent seals make the body fully weather- and coldproof. The K-3 has dual SDHC/XC memory card slots for greater flexibility, with support for wireless memory cards (not included). The large optical viewfinder offers 0.95x magnification and 100% frame coverage when shooting, while the 3.2" 1,037k-dot rear LCD is great for live view and image review.
