Sigma has announced the availability of their 70-200mm f2.8 EX DG OS HSM zoom lens for Nikon SLR cameras. The lens offers optical stabilization (OS), special "FLD" and "SLD" glass elements for improved optical performance, and a 9 blade aperture among other things. Suggested retail price is $2,470US.
A limited number of Sigma lenses when used with the new Nikon D3 digital SLR camera will not support the "Auto DX crop" function. To overcome this problem Sigma will be supplying a free upgrade to existing customers.
