These two lenses are Leica APO-Summicron-SL 35mm f/2 ASPH Lens and Leica APO-Summicron-SL 50mm f/2 ASPH Lens. You can find more from latest interview with Leica manager by LensVids:
Stephan Daniel confirmed that they started talking with Panasonic about 2.5 years ago before Sigma joined the partnership (called the L-mount alliance – a name which we are hoping will change in the future), from our talk with Mr. Kazuto Yamaki, the CEO of Sigma it seems that Panasonic was in contact with both Leica and Sigma separately before the actual alliance was formed and each company didn’t know about the other until a later stage.
In the interview, Stephan Daniel also showed us the new upgraded M10 called M10P (which has a silent shutter and a touchscreen) as well as two new lenses for the SL system (and will soon be available for the Panasonic/Sigma cameras as well) – the first is a very high-quality APO Summicron-SL 35mm f/2 and also a be 50mm f2 APO Summicron-SL. both are not particularly small and it will be interesting to see some more compact lenses for this mount (maybe from Panasonic or Sigma).
