I expect another lens to be announced but not shipping at Photokina this month. Look for a 50mm equilivant of the Leica M 50mm APO for the Leica T. Leica is working on a lens for the Leica T that will be equal to the 50mm APO lens. Equal in sharpness and color rendition. It will not be cheap but no one would expect such a lens to have a bargain price. Oh, and they are working for a maximum aperture of 1.0.
