Just in case you missed today's post on PhotoRumors.com: Carl Zeiss published a new video for their upcoming Distagon T* 1.4/55 lens which they claim to be "the best fast 50mm ever" (see this comparison of seven different lenses for Nikon mount). The Distagon T* 55mm f/1.4 lens is part of a new line of DSLR lenses designed for high resolution DSLR cameras like the D800/D800E. The new lens is expected to start shipping in the second half of the year (probably around September) with a price tag around 3,000 EUR. Few sample images taken with the lens can be found here.
Carl Zeiss also has plans for new high-end 85mm and a wide angle f/1.4 lenses (fast forward to the 1:15 mark of the video below):
