Voigtländer Ultron 40mm / 2.0 asph.

The bright 2.0/40 mm Ultron SLIIs, thanks to its aspherical lens element, offers the ideal combination of compactness and top imaging performance, making it a perfect companion for reportage photography with a full-frame SLR. The Ultron with Nikon mount also features an integrated CPU that communicates with the camera's electronics and informs the exposure system about the set distance, which contributes to more precise flash control, among other benefits.
