Pairing an ultra-wide focal length with a bright maximum aperture, the Ultron 21mm f/1.8 from Voigtlander is a versatile lens designed for M-mount rangefinder cameras. Its expansive field of view is well-suited to architectural and interior subjects while the bright f/1.8 maximum aperture benefits working in low-light conditions. One aspherical element is featured in the optical design to help reduce spherical aberrations in order to produce greater sharpness and clarity throughout the aperture range. The lens also features a manual focus design, which permits working with subjects as close as 1.6' away, and it has a built-in lens hood to shield the front element and minimize lens flare and ghosting.

  • Fast f/1.8 maximum aperture benefits working in difficult lighting conditions.
  • One aspherical is featured to control spherical aberrations and distortion for improved sharpness and clarity.
  • Manual focus design enables a minimum focusing distance of 1.6', and it is rangefinder coupled for accurate focusing to 2.3'.
  • Built-in, non-removable lens hood helps to prevent lens flare and ghosting for increased contrast and color fidelity when working in strongly lit conditions.
