Despite having already announced plans to release a full-frame model in 2015, Ricoh is adding another APS-C K-mount body its lineup.

The new Pentax K-3 II offers some compelling upgrades when compared with the K-3, including an integrated GPS, improved shake reduction, and a high-resolution capture mode that’s not far off in concept from what we saw in theOlympus OM-D E-M5 Mark II.

Aside from that, the weather-sealed K-3 II is very similar in design to the original K-3. It does omit an in-camera flash to make room for the GPS module, but aside from that the body design is pretty much the same. It uses the same 24-megapixel image sensor, powered by a PRIME III image processor that supports shooting at up to ISO 51200. The 27-point autofocus system is unchanged, and the rear 3.2-inch 1,030k-dot LCD is identical to the one used on the K-3. Ricoh states that autofocus performance, especially when tracking subjects, has been improved, and continuous shooting tops out at 8.3fps.

The marquee new feature is what Pentax refers to as the Pixel Shift Resolution System. It works similarly to the Olympus E-M5 Mark II in that it shifts the image sensor by one pixel, rattles off four quick shots, and then combines the images into one file in-camera—it’s only useful for static subjects when shooting with a sturdy tripod. But unlike the Olympus, it doesn’t output a file that’s higher in resolution than the image sensor.
