The Pentax flagship DSLR, now from Ricoh, uses a 24 megapixels APS-C CMOS sensor which can capture images at 8.3 FPS with ISO from 100 to 5,1200. Paired with a high-speed mechanical shutter with 1/8000s to 30s, plus bulb, shutter-speeds, the K-3 can freeze the fastest action and photograph in extremely low-light. This is further helped by its built-in image-stabilization and ultra-sensitive 27-point SAFOX XI autofocus system.
This professional DSLR offers a number of highly innovative feature, including totally unique Anti-Alias Simulation which lets the K-3 maximize captured details or reduce the chance of moire. An interactive demo of this system is included in the Ricoh Pentax K-3 review.
The extensive review of the K-3 published at Neocamera also covers differences between the K-3 and K-5 IIs which highlights the first imprint of Ricoh onto the Pentax original design. This is definitely worth a read for current Pentax owners. As always, a gallery of full-resolution images is included with the review with samples from the entire ISO range. A bonus page compares the performance of the K-3 and Nikon D610 which boasts the same resolution but on a larger full-frame sensor.
