A uniquely versatile super-wide lens, the Tri-Elmar-M 16-18-21mm f/4 ASPH. from Leica allows you to work with three separate focal lengths within one lens. The optical design, which includes a pair of aspherical elements, notably reduces distortion for clean, accurate rendering of interior and architectural subjects, and the aspherical elements also promote a more compact form factor. Seamless switching between 16mm, 18mm, and 21mm focal length positions is possible while retaining a minimum focusing distance of 1.6', and a floating elements design is used to maintain image quality even at close range.

Unique three-focal-length lens gives you the option to seamlessly switch between the 16mm, 18mm, and 21mm focal length positions to adjust your field of view.
Super wide-angle lens has been designed to notably reduce distortion and field curvature to suit photographing interior and architectural subjects.
Two aspherical elements are featured to limit spherical aberrations and improve sharpness and clarity throughout the aperture range and at each focal length setting.
An internal manual focusing design is used along with a floating elements system to achieve consistent image quality throughout the focusing range at each focal length, even at the minimum focusing distance of 1.6'.
The aspherical elements also contribute to a more compact form factor.
The front of the lens is male threaded to accept the included lens hood or an optional 67mm filter holder.
