In an article on the Adorama Learning Center, Mason Resnick says of the new K-1 DSLR, "Somewhat bigger and heavier than Pentax's top APS DSLR, the full-frame K-1 is built around a high-resolution 36.4MP sensor, putting it in direct competition with the Nikon D810 INKD810AD and Sony A7R ISOA7RC. When it comes to Canons, it falls between the 5DS and 5D Mark III. With an ISO range of 100-204,800 and a mechanical shutter that ranges from 30-1/8000 seconds, the camera offers EV compensation to +/0- 5EV."

Like other Pentax DSLRs, the K-1 features built-in sensor-shift shake reduction (SRII) that works on five axes. Similarly, the camera uses Pixel Shift resolution to effectively improve image quality, which uses micro-movements and computational imaging technology to increase subject sharpness.

The Pentax K-1's TTL metering system uses an 86k-pixel RGB sensor with multi-segment, center-weighted and spot metering. The focusing system is a TTL phase detection type, with 33 focus points, 25 of which are cross-type points in the center. The 3.2-inch, 1,037k dot resolution LCD monitor can flip out diagonally as well as horizontally and vertically. Indications include focus peaking, which is useful for manual focusing, face detection, and compositional aides.

The Pentax K-1 also includes wireless connectivity. Geotagging is available via GPS so photographers can record latitude, longitude, altitude, time and direction. The camera has dual SD/SDHC/SDXC memory card slots, and users can select them to be filled simultaneously (JPEG and RAW recording), copying images from one card to the other, or sequentially.

Built on a metal chassis with magnesium alloy shell, the Pentax K-1 is fully weather-sealed against dust and rain via 87 special sealing parts. it can be operated at 14-104 degrees F. At 32.6 ounces it is a substantial camera.

Further expanding the Pentax ecosystem for the K-1, Ricoh has also just announced two new pro-level zoom lenses.
