Leica have announced they are no longer producing this lens 

With its impressive angle of view of 107?, this new TRI-ELMAR conquers 16 mm super wide-angle photography in 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.

This lens is supplied WITHOUT finder.

Leica Camera has introduced a next-generation model of its classic M lenses:
the Leica Summicron-M 35 mm f/2 ASPH.each delivering enhanced image performance and quality, thanks to their new optical design.

The impressive Summicron-M 35 mm f/2 ASPH. fast, classic prime lens delivers superior image performance and a unique bokeh. Despite its high speed and exceptional image quality, its dimensions are astoundingly compact. Furthermore, with its eleven blade iris, this new generation lens creates a circular aperture, lending out of focus areas an extremely smooth look and feel. Images are pin-sharp with rich contrast, and almost completely free from distortion with superb bokeh at all apertures and distances and even when shooting wide open.

The compact APO-Summicron-M 35 f/2 ASPH. pushes the limits of the technology to deliver uncompromising optical performance. With a minimum focusing distance that is rarely found within the M-System, the new lens provides an even greater scope for creativity.
A masterpiece of German engineering for next-level authenticity.

The ten lens elements are divided into five groups; three elements feature aspherical surfaces (one of them on both sides). Six elements are made of glasses with anomalous partial dispersion, which not only reduce chromatic aberrations to almost zero, but also provide apochromatic correction ?a quality that is rarely found in lenses of this focal length.

Close focus distance up to 0.4 m

Possible by a patent-pending double cam unit newly developed by Leica engineers. As a result, the rotation angle of the focus ring could be almost doubled to 176°in comparison to the previous model – with the same compact size of the lens.
