As far as I\'m aware, the 20 remains available only with a GF1, although it\'s supposed to be available soon on its own.
The 20mm can definitely be bought as lens only without having to break up a kit. On Thursday/Friday B&H had it. Amazon has been getting pretty regular orders along with independent stores. Best way to get it is pre-order or at the very least get email notification from B&H.
Yeah, I ran across one locally yesterday. They just shipped last week.
