Sigma Launches Two New HSM Lenses Suitable for D40/D40X
Sigma introduces two new lenses suitable for all Nikon digital SLRs, including the D40 and D40X
Both the new 18-50mm F3.5-5.6 DC and 55-200mm F4-5.6 DC feature HSM or Hypersonic Motors; similar to Nikon's Silent Wave coreless lens drive. Previous iterations of these lenses had been mechanical screwdrive, which meant they would mount, meter but not autofocus on the latest entry-level Nikon bodies like the D40 and the D40X.
