Just posted: Zeiss 15mm f/2.8 Milvus Lens Review.
This review did not have the typical Zeiss ending.
The Zeiss 15mm f/2.8 Milvus Lens is in stock at B&H (available used also), Amazon and Adorama.
Note that the Zeiss 15mm f/2.8 Classic Lens is currently available and is a bargain at B&H (used also available) and Amazon. A specially modified version (shade removed) is available for a $500 premium over the Milvus lens at Adorama.
