Hmmm...that's a good question. Looking at the SNR curves, the K-5 and D7000 are similar up to ISO 1600, yet the A55 is consistently lower by about 1/3 of a stop, which is exactly the amount of light lost to the pellicle mirror. And while we're looking at this graph, note how the K-5 improves S/N over the D7000 beyond ISO 1600; it's only about 1/3 stop, so it might not be noticeable in images, but it's there. I'm curious as to what Pentax did to get that break in the SNR curve at ISO 1600; I wonder if they used extra magic smoke... --M. -- \/\/o/\/\ --> http://WorldOfMiserere.com http://EnticingTheLight.com A Quest for Photographic Enlightenment -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
