Lens Description: The Sigma 120-300mm f/2.8 EX DG OS APO HSM AF provides a large constant f/2.8 maximum aperture at all focal lengths. In essence, it transforms a large-aperture 300mm f/2.8 lens into a zoom lens that allows you to determine the picture composition without having to change your vantage point. Optical image stabilization facilitates hand-held photography by allowing you to shoot at shutter speeds 4 stops slower than without the stabilization.

At half the cost of Canon or Nikon 300 f2.8 (stabilised), this lens sure looks interesting (very heavy mind you). If the 300 f4 VR doesnt materialise any time soon, this could be an attractive alternative. Many claim very good performance.

But wait Nasim! With the release of the new one with USB dock corfirmed for mid May, it would be a good opportunity to do a face off and see what Sigma has to offer. Maybe a good reason for once to go arftermarket…

thanks!

I bought one of these at a garage sale. This older version is NOT image stabilized as is stated in the specs. The later version is. I have to use a very fast shutter speed or a monopod or tripod. But, for the price I paid I can live with it to take baseball pics of the grandkids.

There are three versions, the first was not stabilized (EX DG HSM), the latter two ARE (EX DG OS HSM, DG OS HSM S).
