The new Sigma 17-70mm f/2.8-4 DC Macro OS HSM lens is now in stock for Canon mounts at both B&H and Adorama.
It also appears to be in stock in the Sony mount option here at Adorama. Note that the Sony version does not include Optical Stabilization due to the built-in stabilization in Sony Alpha cameras; however, Sigma still prices the Sony mount version at the same price of the other OS versions.
All the other mounts are available for pre-order here at B&H or here at Adorama.

Pricing and availability are now official for the new Sigma APO Macro 180mm f/2.8 EX DG OS HSM lens. It will be available on July 27 for $1699 for Canon, Nikon, Sigma, Sony and Pentax mounts. It’s currently available for pre-order at B&H Photo.

Earlier this week, Sigma announced a 150mm f/2.8 Macro lens with its great HSM AF motor inside. The new macro lens offers a 1:1 magnification ratio, along with a 9-blade circular diaphragm.
While Sigma showed off the new lens at Photokina 2010, it has not released further details concerning its price or availability. For the sake of reference, the current 150mm f/2.8 Macro lens is available in Canon, Nikon, Olympus and Nikon mounts and carries a street price of around $730.
