Good morning,
I think the new Zeiss Distagon 1:1,4/55mm is a derivate from the former Hasselblad Distagon 1:2,8/50mm - which has it's own logik to use a good medium-format design for 35mm-use as done before with the lens-elements in the Hartblei-Superrotators. The dimensions of such a lens is the other side of the medal - it has medium-format-size, explaining the 82mm-diameter of the filter. The weight will be the next point - nearly 1000g I estimate.
The use of only the center area of a theoretical 60x60mm-area helps to eliminate disturbing effects from the outer regions and uses only the best performing zone of the lens. The reduction of vignetting is a further advantage, so that the caim for superior performance with 35mm-dslr is to believe ...
My own experiences with Hasselblad Planer 1:2,0/110mm, Sonnar 1:2,8/150mm and Tele-Tessat 1:4,0/250mm on various film and digital EOS-bodies let me expect superior performance - but also superior pricing ...
I'll be there at Cologne - we will see ... - together with the other announced new products a very interesting photokina, as it seems.

"A must-see attraction is a high-performance, full-format SLR camera lens with manual focus. With a focal length of 55 mm and aperture of f/1.4, this lens is the first model of a new product family designed for demanding users. Thanks to a newly developed optical design, this lens is superior to conventional full-frame lenses, and it achieves with powerful full-frame, full-format cameras an image performance that until now has only been seen with medium-format systems."
real deal of fluff? cost estimates? Am i reading the lens correctly? 82mm filter on a 55mm 1.4?
