Had to happen I guess, the factory is saying that the pricereductionslashannihilation is due to lowered production costs but methinks it may have more to do with new models on the market ( think D800 ) and the fact that Sigma have probably sold the SD 1 in figures that you can count on 10 fingers and 10 toes.
If only they had made it to accept a variety of lenses, Minolta, Pentax, Canon and Nikon. Then it would have been a lot more appealing to people.
