Los Angeles-based consultancy Black Design Associates, LLC, have just announced a concept (I repeat, concept) for a hybrid iPhone / Leica. The i9 is essentially a fully-featured iPhone 4 accessory, intended to elevate a smartphone to the ultimate prosumer toy.
And lest the i9 comes off as a glorified protective case, Black Design have retooled Leica's CMOS image sensor and lens, with effective 12.1 MP lens, 8× optical zoom, 35 equivalent focal lengths and ready-to-shoot operation (including 0.3s start-up). I gotta say, the shared battery capability—either one of the devices can power the other as necessary—is also a nice touch.
