PDN Pulse already published their Pentax K-1 article online – check it out here:
“Ricoh has made its long-awaited foray into full frame photography official today with the launch of the Pentax K-1 DSLR, which is due to arrive in April for $1,800 (body).
The K-1 sports a 36.4-megapixel full frame CMOS sensor with no optical low pass filter and a native ISO range of 100-51,200. The image sensor can shift to provide 5-axis image stabilization with up to five stops of image correction, per CIPA standards. It also supports a Pixel Shift Resolution mode (similar to the one we tested on the K-3 II) where the sensor shifts by one pixel over a series of four images which are then merged in camera to create an image with less noise and more accurate colors.”
