Voigtlander 21mm F/1.8 Ultron

The Voigtlander 21mm f/1.8 Ultron is a fast-aperture wide-angle prime lens for Leica M-mount cameras. Key features include:

• Great for low-light and shallow depth-of-field photography

• Manual focus ring and half-stop aperture clicks

• Rangefinder coupling

• Durable, high-quality metal build

Rangefinder Coupling. The Voigtlander 21mm f/1.8 Ultron offers rangefinder-coupled focusing from 0.7m to infinity, with an additional close-focusing option down to 0.5m using the hyperfocal distance method.

Fast Aperture. The fast f/1.8 aperture allows you to capture images with a shallow depth of field, providing smooth background blur for true subject isolation. It’s great for low-light photography.

High-Quality Build. This lens features a sturdy, high-quality metal build with a smooth, long-throw focus ring and half-stop aperture clicks for minute adjustments. It features a built-in petal hood to help minimize lens flare, and its eleven-group/thirteen-element optical design features one aspherical element to keep aberrations at bay.

Built-In Finder Lines. Many people shoot with the 21mm estimating from the widest set of built-in finder lines, but others prefer an externally mounted viewfinder.
