Optical Distortion for Voigtlander FE 35mm f/2 APO-Lanthar Aspherical

In addition to its other world-class qualities, the Voigtlander 35mm f/2 APO-Lanthar has near-nil distortion for near-perfect accuracy of rendition. Along with its exemplary APO correction and world-class sharpness, its rendition is as close to natural as any lens is going to get.

The freedom from optical distortion also means that real sharpness is substantially better than most lenses in practical terms: no need for distortion correction means no loss of micro contrast from the stretching-apart of pixels. Compare for example to the Sigma FE 35mm f/2 DG DN Art, which throws away significant performance by such a strong warping of the image so as to require distortion correction.
