A Close Look at the Pentax K-1's Internals
High-res photos and component breakdown
The Ricoh Imaging booth at CP+ 2016 placed a heavy emphasis on the recently-launched Pentax K-1. Today we take an even closer look at what's on the inside of the Pentax's first full frame DSLR.
Most of the technology inside the K-1 was either developed from scratch or updated specifically for this new body. A special display case on the show floor allowed us to gain valuable insight about what's found under the hood.
New SR II 5-Axis in-body stabilization
Perhaps one of the most exciting additions is the new five-axis Shake Reduction II (SR II) system. In addition to offering an extra stop of compensation over previous models (up to 5 stops total), SR II compensates more effectively for camera roll.
Suppose that a photo would normally require a shutter sped of 1/500s to appear sharp; with Shake Reduction, it may well be sharp at 1/15s.
Full-frame sized pentaprism (0.70x magnification, ~100% coverage)
A larger chunk of glass is needed for a full-frame optical viewfinder. The K-1's pentaprism offers nearly full coverage of the image area and the viewfinder image is almost twice as large as that of APS-C bodies (despite a lower magnification rating).
Pentax Real IMage Engine IV processor
The latest-generation Pentax CPU is dubbed "PRIME IV". It enables the largest-ever continuous shooting buffer in a Pentax DSLR.
36.4-megapixel 35.9 x 24.0mm CMOS sensor
At the heart of the K-1 lies a "newly developed" 36.4-megapixel CMOS sensor. Community sources suggest that the chip is manufactured by Sony. The sensor supports an ISO range of 100 to 204,800 (the highest in its class).
Expect the K-1 to be able to take a beating thanks to a magnesium alloy body, metal chassis, and weather-sealed construction.
The camera's rear LCD hinges are just as tough as the body itself. These hinges have been designed to support the entire weight of the camera plus a reasonably-sized lens. Of course, this isn't a typical use case, but the flexibility for a user to quickly grab the camera by the LCD could for instance save the camera from an unfortunate drop while in the field.
Newly-developed shutter mechanism
The shutter mechanism is another piece of hardware that must be re-worked for a larger image format. Furthermore, the K-1 allows for flash synchronization up to 1/200s, an improvement over the previous limit of 1/180s.
All this shows that a considerable effort was put in to the K-1's development. It's now evident why Pentax couldn't "just release" a full-frame two or three years ago. Even today, users will get a lot of technology for the K-1's comparatively low launch price of $1799 (USD).
