I came across this tweet earlier today referring to one of the Leica T press photos (above) that contains a new/not-yet-released 35mm f/2.0 Summicron M lens:

For comparison, here is a picture of the current Leica 35mm f/2.0 Summicron M Asph lens:

Even the 28mm M lens of the left looks different than the current 28mm Elmarit or Summicron versions (update: it’s an older model). A while back Leica introduced a new 28mm limited edition Summicron M lens with a new hood design, but the lens never made it to mass production.
