I was cruising the net looking at lens review sites, and happened on a 20D review. On it is a table with different cameras and their pixel sizes. Kind of hard to believe, but the Sony f828 has a 2.7 micron pixel size. No wonder the damn thing has so much noise.
What I have to wonder, is IF the 828's imager was a 2/3" CMOS imager. I reported during Photokina about OmniVision and their 5MP 2.775 micron CMOS sensor. Should be interesting for what and on what camera it's used.
