The announcement of the Voigtländer 10mm and 12mm hasn’t been handled well because there is a lot of confusion being generated by the new E-mount variants of Voigtländer lenses. Initially, it was believed that both the M and E mount 10mm lenses would be $899, but that misconception has been corrected. The Sony E-mount edition will retail for $999, which was confirmed by B&H Photo where you can preorder.
So what does the additional money and less adaptable mount get you? The translation of DC.Watch’s coverage of the Voigtländer 10mm and 12mm indicated that the E-mount lens is optically different from the M-mount variant and that it will be electronically connected to your Sony body, so there will be valid exif data available, without having to do additional work after shooting. Further, the manual that is now available corroborates DC.Watch, but it is difficult to determine if the optical differences will lead to improved image quality. I am going to try to get a copy of both at the same time to compare them directly. Shipping is expected to start this month.
