The Pentax K-3 is a 24-megapixel Pentax high-end digital single-lens reflex camera with an APS-C sensor, announced on 7 October 2013.[1] The Pentax K-3 is the successor to both the K-5 II and K-5 IIs models, which have a 16-megapixel sensor. The K-5 II (and most other cameras of its time) had an optical low pass filter or anti-aliasing (AA) filter that can prevent the appearance of moire patterning on the captured image. This filter reduces the sharpness of the image, so Pentax also produced the K-5 IIs which omitted this filter. In the K-3, Pentax obviated the need for providing two separate models by including a selectable AA filter "simulator". This mechanism vibrates the sensor when switched on, slightly blurring the image in a way that replaces the function of the optical AA filter, providing the same benefit as the filter in the K-5 II and other cameras with an optical AA filter. When the AA simulator is disabled, the sensor records a sharper image, as in the K-5 IIs.
The Pentax K-3 was also the first camera to support the Pentax FluCard for wireless remote capture and download of images.
The Pentax K-3 is a mid-size DSLR with a weather-sealed magnesium alloy body, and is priced at a relatively similar level to the newer upper-entry level Nikon D5500 DSLR[2] and $300 cheaper than the newer mid-range Nikon D7200 DSLR. The Pentax K-3 was ranked #2 in a comparison of mid-size DSLR class, was class-leading in image quality for portrait, street, daily and landscape photography, and ranked only slightly lower for sport photography. In-body stabilization also gives the Pentax K-3 an advantage, but its 800-gram weight is slightly more than average for a mid-size DSLR.[3]
