Of most interest to Nikon D3 owners, Sigma announces a fast standard prime lens with a HSM motor, filling a gap that Nikon has left wide open for years.
If it’s as good as Sigma’s 30mm f/1.4 lens for DX crop cameras, then this should be a big winner. I know I’d get one if I was buying a D3.
Sigma have added HSM focusing (AF-S) to their 18-50mm f/2.8 and 17-70mm f/2.8-4.5 lenses, making them compatible with the Nikon D40 and D40x auto-focusing and also have full time manual focusing override.
Considering theses are optically very close to my prized Tamron 17-50mm f/2.8, this is a very good move by Sigma.
