Noise

JPEG images from the Pentax Prime III processor can have multiple issues which cause a lack of detail in images such as clipping in colour channels and in-camera noise reduction. However, it’s possible to control noise and achieve detailed images shooting in raw and post-processing.

At ISO sensitivities between ISO 100-800, there is some luminance noise present in the raw files but it’s very slight and only obvious at ISO 1,600 and above. I would happily use this camera right up to 6,400 without worrying too much about colour or luminance noise, but thereafter I would take measures to keep it lower.

Below are 100% crops from our test scene across the full range of ISO sensitivities.
