Now that the Sigma 18-35 is out, I can see people running out and buying an APS-C DSLR body just to be able to use it. This really is impressive! Dpreview likes the lens. Were they to make this for Micro Four Thirds it would great. Guess what lenses I would no longer need? Not many of them! I'm not sure it would be a 1.8 though. My question is, however, what cameras does this fit on? I can't really adapt it (nor would I want to. To me the trade-off for for weight, size, and no AF is price). It won't fit on the Sony NEX, right? What about that Nikon 1 Austin Kucher POS? I mean the lens looks great. But I'm not about to buy a Nikon or Canon DSLR. Ever. If I did it would be full frame.
