Leica's surprise announcement of the Leica S2 pretty much blows the bubbles off every other press release coming out of Photokina, or anywhere else in the photo world as of late. Sure, reasonably priced, full-frame DSLRs are cool; but a 37.5-megapixel medium-format sensor that's 56% larger (30 x 45 mm) than the so-called competition, and in a smaller body no less, is downright awesome.
