Voigtlander 21mm Ultron NEX Friendly?

Voigtlander 21mm f/1.8 Ultron

Here is a new Leica M mount lens from Voigtlander. It is a fast f/1.8, 21mm wide angle lens. This translates to 30mm (effective FOV) for the Sony NEX sensor. The big question is, will it play well with the APS-C sensor? We are hoping that it does and give us a fast, wide angle lens similar to the Zeiss 24mm f/1.8 ZA E. The manual focus and aperture, Leica M mount, Voigtlander 21mm f/1.8 Ultron will cost £1149. It is almost twice the weight of the Zeiss 24mm.
