With its impressive angle of view of 107°, the Leica Super Wide Angle Tri-Elmar-M 16-18-21mm f/4 Manual Focus Lens delivers perfect Leica M style. Due to the minimal distortion and barely perceptible field curvature, it can be recommended for highly demanding architecture photography even at the 16 mm setting. Used on the digital M8, it produces the image effect of a 21 - 28 mm lens, still enabling extreme wide-angle views. The ultra compact shape is achieved by two aspherical elements. A new design of the interior focusing significantly enhances the quality in the close-focus range through an adaption of the floating element principle. Brilliant field depth can therefore be used from a distance of 0.33 m for hyperfocal photography. Save money by buying the lens in a set together with the Universal Wide-angle Viewfinder M.
