The Voigtländer Super Wide Heliar 15mm f4.5 is a very compact full-frame ultrawide lens for Leica thread mount. Including the hood, this thing's only 3.5cm long and weighs just over 100g. Tradeoff? Well, there's no rangefinder coupling, so you'll have to guess focus. And the lens protrudes into the camera body a fair bit, which is fine for film cameras but may cause vignetting on digital cameras. In excellent condition, with smooth focusing and only very minor cosmetic wear. Glass is clean, with light dust. Includes the original slip-on viewfinder and M mount adapter.
