Nikon PC-E Nikkor 24mm f/3.5D ED Tilt/Shift lens
UPDATE from yesterday: Nikon has the 24/3.5 on its web site now, along with the press release. Bjørn Rørslett of naturfotograf.com has some comments on the new lenses (“New Lenses from Nikon”). And if you haven’t read his Nikon D3 review, it’s well worth reading.
