I posted that on PhotoRumors already, but since many Nikon fans are expecting an updated 35mm f/1.4 lens from Nikon, here is a Zeiss rumor for you (you will still get only manual focus with a Zeiss lenses, which you can also get with the Nikon 35mm f/1.4 AI-S lens):
In his Leica M9 & Nikon D3x comparisson Erwin Puts wrote:
"Lenses used are the Summilux-M 1.4/35mm asph and a very new redesigend Zeiss Distagon 1.4/35 with Floating element."
The above sentence was removed from the article after it appeared on the FredMiranda forum.
Zeiss currently have a 35mm f/2.0 Distagon T* ZF lens (ZF models are for Nikon F mount).
