See my Pentax K1 wish list at B&H Photo.
File quality of the Pentax K1 is amazing. In this piece, I show the RawDigger histograms for all ISO values, including histograms for dark tones which show the best (smoothest) pixel quality I’ve yet seen from a 35mm full frame camera—even through ISO 800.
In addition to the RawDigger analysis, entire frame images are shown at 58% of actual pixels (12.4 megapixels) as well as 12.4-megapixel actual pixels crops, all from ISO 100 through ISO 204800.
In my review of the Pentax K1:
The Pentax K1 has a mighty impressive sensor even in its StdRes mode. SuperRes pixel shift mode is even better, but cannot be used when there is any change in lighting intensity or color, as was the case here.
