Once again you have to give Pentax credit for results that - whilst undoubtedly noisy - are much better than what we've come to expect from a camera in this class, thanks to the fairly subtle luminance noise reduction and effective removal of chroma noise, whilst retaining a decent level of detail. With cameras like this you can't - unfortunately - expect a lot from anything over ISO 200, there is always going to be the compromise between the inevitable problem of noise and the detail destroying effects of heavy-handed noise reduction. I think the Pentax engineers have struck a happy medium that produces results that look 'grainy' but still have enough detail to produce a decent print.
