Zeiss will announce a new Distagon 55mm f/1.4 ZF.2 lens (Nikon mount) at Photokina. The lens will be available for sale in the second half of 2013. Zeiss already has two 50mm lenses in their lineup: Planar T* 50mm F/1.4 ZF.2 and Makro-Planar T* 50mm f/2 ZF.2 (check this comparison of seven 50mm prime lenses for Nikon F-mount).
The company also announced plans to produce lenses for mirrorless cameras. No other details were given at that point – it will be interesting to see if Nikon 1 will be included.
