I'm not sure what portion of the information that Pentax is using a 22bit A->D converter in the K10D is either marketing hype or horsepucky. They use a higher bit space A->D converter to allow greater accuracy in the transform from voltage to discrete intensity values, it's produces a higher resolution fit to the voltage potentials which are sampled down to the 12 bit output quantization space. What practical value this lends is contributory to the K10D's excellent image qualities and in-camera image processing capabilities. Yes, there's marketing hype associated... but that's assumed. ;-) G -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
