Larry, your numbers are slightly off. When Pentax introduced the K20D they said the sensor had been designed such that the inter-photosite spacing (taken up by circuitry) was reduced. They claimed the photosites on the K20D sensor were the same size as those of the K10D thanks to this improvement. http://pentaxdslrs.blogspot.com/2008/11/does-pentax-k20d-perform-better-with.html More info on the Japanese Pentax K20D site: http://www.pentax.jp/english/imaging/digital/slr/k20d/feature.html http://www.pentax.jp/english/imaging/digital/slr/k20d/image/fea_02-1.jpg I hope you found this useful :-) --M. -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- http://www.EnticingTheLight.com -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -- 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.
