There are reports of two new third party lenses for Nikon F-mount expected to be announced in the next few weeks: Sigma 100-400mm f/5-6.3 DG DN OS: The lens should be announced soon, probably in the next 1-2 weeks Tokina ATX-i 11-20mm f/2.8 CF (pictured above): The lens will be launched in July Aperture ratio: f/2.8 Optical construction: 14 lenses in 12 groups Angle of view: 104-72° Aperture blades: 9 Minimum distance: 0.28 m Filter size: 82 mm Lens length: 94.3 mm (Canon), 91.8 mm (Nikon) Weight: 570 g (Canon), 550 g (Nikon) Other: lens hood, front and rear covers included Available for Canon EF and Nikon F Price around €600 Lens design: For comparison, here is the lens design of the current Tokina AT-X 11-20mm f/2.8 PRO DX model: The optical design looks identical.

The coating also makes cleaning the surface easier. The Nikon version of the Tokina has a silent drive focusing motor (SD-M) in combination with a GMR sensor. Apparently the predecessor didn't have that. This explains the changes in dimensions and weights.
