Product Overview

Leica Super-Elmar-M 21mm F3.4 ASPH is a manual-focus ultra wide-angle prime lens for Leica M-mount. It covers the full-frame image circle. Introduced by Leica in 2011, it has 8 elements in 7 groups.
As an ultra wide-angle prime lens that is quite compact, the Leica Super-Elmar-M 21mm f/3.4 ASPH can be an interesting supplement for those occasions where a normal lens just won't do. 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.
