Folks, available for sale is a "like new" Sony E-mount to A-mount adapter. The Sony part# is LA-EA1.
Note that unlike adapters to other mounts, which are at best simple mechanical couplings, this adapter is something that fully communicates back-and-forth between the NEX cameras and the A-mount lenses, electronically, with full aperture control. The EXIF data clearly shows that.
Auto-focus is not available at this time, even though in an interview, Sony Imaging's top boss (Toru Katsumoto) seem to indicate that a future firmware upgrade might introduce Auto-focus between NEX and A-mount lenses, when connected via the adapter.
Listing this for $150 shipped, via FedEx Ground. Add 3% for paypal, if paying by credit card. Currently looking only at folks from the continental US (lower 48 states).
