Bigma has shed some weight and picked up optical image stablization.
The first version of this lens earned the nickname Bigma for its 4.25-pound heft and huge size.Now comes Son of Bigma ($1,600, street), lighter at a little less than 4.2 pounds, yet with a number of optical improvements including image stabilization.Like the original, this 50–500mm boasts the broadest zoom range—10X—of any Sigma full-frame lens. That’s far more range than the Canon 100–400mm f/4.5–5.6 IS (4X) or Nikon 80–400mm f/4.5–5.6 VR (5X) stabilized full-framers.
