Voigtlander 21mm Ultron Aspherical on Sony NEX-7

NEX-7 with Voigtlander 21mm f/1.8 Ultron via Novoflex Leica M to E-mount adapter.

TechTalk with Ron Sheffler tested the new Voigtlander 21mm f/1.8 Aspherical Ultron against three other Leica M 21mm lenses on the Leica M9. He also used the lenses on the Sony NEX-7 and found that the Voigtlander 21mm f/1.8 the best at farther distances and large apertures. The Leica 21 f/3.4 Super Elmar-M came in second, the Zeiss 21mm f/2.8 Biogon in third, and the Leica 21 f/1.4 Summilux at the back of the pack. At f/4 all the lenses performed equally well on the NEX-7's APS-C sensor.

Here are some samples from the NEX-7 and the Voigtlander 21mm wide open at f/1.8. You can see more samples at TechTalk.
