Carl Zeiss: ZF glass for Nikon F-mount

For the first time, Carl Zeiss announces the launch of ZF, a new range of interchangeable Zeiss lenses for Nikon F-mount cameras - both analog and digital SLR! first releases will be the fast PlanarT* 50mm f1.4 ZF ; to be followed by the PlanarT* 85mm f1.4 ZF supposedly a great portrait and story-teller lens. both lenses will become available by mid-2006.
as a present Nikon D70 user, i'm obviously keen on that Zeiss 50mm prime lens. but the b!g question is: how are these gonna compare with Nikon's acclaimed nikkor 50mm and/or nikkor 85mm glass?

my first encounter with Zeiss lens dates back to year 2000, when i had my 1st digicam - Sony DSC-S70, a rather novelty item back then. this 3.3MP compact boasts full movie/sound capability, and a razor-sharp Zeiss lens! S70 produced consistently brilliant images, let down only by its annoying shutter lag (typical problem with older gen digicam) otherwise an awesome little camera.

then came Sony DSC-S85 in 2002. slightly smaller than S70 in dimension, this 4.0MP black beauty felt equally robust. sporting the same 7-21mm (34-102mm equiv.) Zeiss Vario-Sonnar lens, pic quality was as sharp and crisp albeit noisier (at ISO >200) owing to a million more pixels being crammed into its puny sized ccd. shutter lag time improved marginally, but S85 can still be frustrating to shoot with.
