First announced back in February, Sigma has just sent their newest macro lens out into the wild, and the lens is now available from the usual outlets for $1,400. The new Sigma 105mm F2.8 EX DG OS HSM Macro can be purchased on a Sigma, Canon or Nikon mount, depending on your preferred body, and can focus down to 1:1 magnification at 12.3 inches.
The 105mm is designed for full frame cameras, so when mounted on a cropped sensor, the effective focal length shifts to 150mm. This is only the second prime macro that Sigma has made which includes image stabilization — in this case, Sigma's Optical Stabilizer (OS) technology. The minimum aperture on this lens is f/22, and it has a floating focus system to help you get a razor sharp look, and limit optical aberrations. Those of you obsessed with bokeh will doubtless enjoy the pleasantly smooth blur from the rounded nine-blade diaphragm.
Included in your purchase are a hood adapter, lens hood, front & rear lens caps. You can see a review of one of the antecedents to this lens with our buying guide look at the Sigma 105mm f/2.8 EX DG Macro, a significantly cheaper, lighter, but much less technically advanced lens.
