That argument is starting to be like telling someone that if it rains things may get wet. The K-5 sensor has a higher pixel density than any other APS-C sensor Pentax has used. Yet it has the lowest noise of any APS-C sensor they've used. Is that correct? So obviously that argument doesn't hold true across the board. One can have high density sensors and low noise. The real issue is, at what point does noise become unacceptable and wipe out the benefit of increased pixel density? I submit it depends on the photographer, the subject, and all the other shooting conditions, ISO, aperture, and shutter speed playing a larger factor. I also submit that if Pentax releases a higher than 16MP APS-C camera you'll purchase one, because they can't keep making 16MP APS-C bodies forever. :) Tom C. -- 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.
