The new Lee Works Noctlux M 50mm f/1.1 lens for M-mount is yet another copy of the Leica Noctilux lens by a new Chinese lens manufacturer (they do not even have a website or social media accounts yet). I think we have already seen a dozen versions of this exact design by several different brands, but it seems that the demand for such lenses is still very strong (they will not make them if they cannot sell them):
