Eddie's take on it
The last lens Sigma released for 4/3 was their standard full-frame 70-200mm f/2.8 zoom. With the 2x crop factor of 4/3, this goes from a standard reportage zoom lens, to a long telephoto, which means its use is completely different than it was originally intended.
This is a very good lens, but ultimately, there is no point in buying it. It has to be slightly stopped down for sharpest results, which means you can simply use the smaller, lighter and absolutely excellent Olympus 50-200mm SWD, which gives you 200mm @f/3.5, just 2/3 of a stop slower, but bitingly sharp wide open.
Because of this reason, not many people bought one, and thus finding it used is difficult. Don't pay absurd prices some sellers ask for it - it is not worth it.
