Edited ISO 819,200 image from Pentax KP.
And after initial reserve over the design of the camera, many now seem to be swayed by its rich features, performance and customisability. Overall, one can’t help but conclude that the KP is a huge advance over the K-70, a remarkable camera in its own right. Pentax cameras offer a lot of configurability of the output, and it’s therefore likely that the saturation compensation can be turned off or on as needed. That being the case, it would be true to say that this will not be an issue once the DxO software is updated to support the Pentax KP. As explained by a commenter over on Imaging Resource, this may be due to the KP using a different white point in its raw output compared to previous Pentax cameras. The current version of DxO OpticsPro does not include a Pentax KP profile, and some loss of luminance detail could be seen in the PRIME processed image. The in-camera processing deals with this gracefully, so that no luminance detail is lost (KP on left, K-70 on right, both with default in-camera noise reduction): The Pentax KP features saturation compensation, to stop colours looking washed out at higher sensitivities. The out-of-camera JPEGs retain a little more detail, along with some more noise – probably a matter of personal taste, but I would go with processed raws here.
Since I was able to cheat DxO 11 into processing an ISO 102,400 file, I thought I would post the results of performing PRIME noise reduction on a pair of these at ISO 102,400 – one from the KP and one from a K-70 – click on the image for a 1:1 view of the striking difference (KP on left, K-70 on right):Ĭompare with the out-of-camera JPEG result (KP on left, default in-camera noise reduction on both): Imaging Resource have published RAW samples from the Pentax KP.
