We continue the prime lens party! If you are not interested in the newer Sigma 19mm and 30mm f2.8 DN lenses that go for $200 each, and you prefer to get the older first generation not-metalic versions, you can get them together for half the price of the new second-generation lenses!
The old first-generation Sigma 19mm and 30mm f2.8 DN lenses, bundled together in one product listing, can be yours for $200 total at B&H Photo for the Sony NEX e-mount.
As of a 5:40pm ET recheck, the Micro Four Thirds is not available. I thought it was in-stock earlier today, but I don't take screenshots and my memory is fading, maybe it was not in-stock earlier today, and I was confused *_*
