There is a new Mandler 35mm f/2 lens for Leica M-mount from China that is a replica and a complete reproduction of the optical formula of the original Leica Summicron 35mm f/2 seven-element lens. The name "Mandler" is a tribute to Walter Mandler, who designed many legendary Leica lenses. The details on the new lens can be found here:

Mandler is expected to launch another new lens in July. In the future, they are planning to release 3-4 new lenses per year.
The Mandler 35mm f/2 lens looks very similar to the Polar Solaron-M 35mm f/2 lens for Leica M-mount (previously reported here):
