A non-story story here.
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. And the sharpness you capture will never need to be degraded by distortion correction, as with so many other lenses.
See my comments including what I found at closer range.
Don’t judge by the rain gutters on my old house—they actually are bowed in reality, maybe designed that way for drainage? See my comments in the review page—I used a ruler overlaying the image, and also corrected for the 0.2° off-level.
