Leica Tri-Elmar-M 16-18-21mm f/4 ASPH. Lens with Universal Wide-Angle Viewfinder

Configured for ultra-wide photography with an M-mount rangefinder camera, the Tri-Elmar-M 16-18-21mm f/4 ASPH. Lens with Universal Wide-Angle Viewfinder from Leica bundles the uniquely versatile three-focal-length lens with the Universal Wide Angle Viewfinder for making more accurate compositions with each focal length position.

Tri-Elmar-M 16-18-21mm f/4 ASPH. Lens

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.

Universal Wide-Angle Viewfinder M

The Leica Universal Wide-Angle Viewfinder M is a shoe-mounted external viewfinder for M-system rangefinder cameras (including M8). This viewfinder offers bright-line frames to match the 16-18-21mm lens. Since the 1.33x conversion factor has to be considered for the M8 digital camera, bright-lines for 21, 24, and 28mm are also included. It can also be used with other fixed lenses that match this range. A parallax compensation dial allows for adjustment of the frame to the focusing distance, in five steps (0.5, 0.7, 1, 2 meter & infinity).

The use of one aspherical lens element and one with achromatic correction in the viewfinder makes it insensitive to stray light, and provides a high resolution and exceptional brilliance image.

• An illuminated spirit level helps to keep the camera horizontal even in unfavorable light conditions.
• Compatible with the R8/R9 series of diopter correction lenses.
