Few lucky people have already received their Nikon 50mm f/1.4G AF-S lens and brag about it on dpreview. Bjorn Rorslett has already posted a review of this lens – he rates it 5 out of 5.
For now Adorama and B&H are still only taking pre-orders.
Update: Nikon AF-S 50mm f/1.4G samples available here and here.
