A little used and beautiful Carl Zeiss lens. Comes with the original lens hood, Sigma lens cap (which is much better than original) and the original packaging.
A super wide lens that can close in just over 8". It's non-reflecting and distortion-free, and so outputs images with contrast and colour. Made with floating lens elements, it keeps performance from edge to edge at all distances. A great colour control prevents colour fringes even along high-contrast contour edges.
