This is not true.
Pentax applies NR on RAW data in their Prime engine from ISO 3200 and above only.
Below 3200, there is no NR applied as measured by GordonBGood and stated here:

The lack of pixel sharpness is very likely stemming from a strong AA filter only.[/quote]
Thanks for the link. I trust GordonBGood.
But it's strange that Pentax applies a stronger AA filter than Nikon and Sony. I am curious how the various companies handle the 'bare' sensors sold by Sony. Does each one look for a different company to provide the AA filter and ADC electronics etc?
