Product Overview

Voigtlander 21mm F1.8 Ultron is a manual-focus ultra wide-angle prime lens for Leica M-mount. It covers the full-frame image circle. Introduced by Voigtlander in 2012, it has 13 elements in 11 groups.
Manual focus may be limiting to some, but purists will find it much more engaging. There are also fewer things to go wrong on the long run. The entire lens is crafted out of metal, which imparts a level of tactile sense of quality.
The bright maximum aperture for an ultra wide-angle lens is appreciated for night and astro photography. Even though the lens is not stabilized, at this focal range it does not usually matter. In fact, some may be able to get cleaner corners without image stabilization. Those who like sunstars (sun bursts) will be pleased by the lens' even-numbered aperture count, though conversely those who find sunstars distracting may have the opposite feeling.
