Luminous - Top pros who work with exacting clients, and wealthy amateurs who demand nothing but the best possible image quality have always turned to medium format backs and cameras. Over the years resolution has grown from 16MP, to 21MP, to 39MP, and a couple of years ago to 60MP. Now, with the just announced Phase One IQ180, the company's new flagship, that ceiling has been raised to 80 Megapixels.
Cnet: When describing Phase One's IQ180-based camera system, there are plenty of superlatives you could pick.
If they put the price down little bit, I might think about this :)
