Sigma

The 180mm Macro has been a part of Sigma's stable for a while. But, the new version opens to F/2.8 instead of the slower F/3.5. Sigma also gave it optical image stabilization to help keep things sharp, despite the super-close focusing and the telephoto length. Minimum focusing distance is just 18.5-inches.

Sigma has announced that it will be releasing a new lens for Sony and Pentax mounts to take the place of the 17-50mm f/2.8 EX DC OS HSM lens. The new unit has the eminently memorable name Sigma 17-50mm f/2.8 EX DC HSM, and the main difference between it and its predecessor is that the optical stabilization has been dropped, since Sony and Pentax bodies have stabilization at the sensor level.

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.
