Key Features

Based on core principles of passion for photography, The All New Flagship APS-C model K-3 III continues a heritage of craftsmanship combined with todays new technologies.

The newly designed optical veiwfinder provides a 100% field of view and 1.05x image magnification. The veiwfinder offers a wide viewing angle comparable to full frame cameras with increased image brightness due to the improved reflectance of the pentaprism.

Top ISO sensitivity of 1.6 million provides image capture in low light situations and achieves excellent descriptive power in the entire sensitivity range. Multi-dimensional image space filtering reduces noise while leaving fine contours. It maximizes the resolution performance and reproduces the texture and details of the subject.

IN-CAMERA SHAKE REDUCTION (SR): The PENTAX digital SLR K series cameras are equipped with the SR mechanism built into the camera body. Because shake reduction is applied in the camera body, this means that any lens compatible with the K-Series cameras will benefit from image stabilization.

HIGH IMAGE QUALITY: By using three ED glass lens elements and two super-low dispersion glass lens elements, a clear image is achieved with less chromatic aberration. Thanks to the 20 elements sharp images are captured even at the edges at any given focal length.

HD COATING TO ENHANCE IMAGING POWER: Produce high-contrast images with edge-to-edge sharpness, free of flare and ghost images.
