The Voigtlander Ultron 35mm f/2 Aspherical Type II - Leica M Fit is a compact semi wide-angle lens with a new optical design consisting of 8 elements in 5 groups. By limiting the maximum aperture to a practical level, the lens realises both compactness and high performance. While the optical design features an element with aspherical surfaces to ensure optical performance that can be used with confidence from maximum aperture.
