Probably it's a very old model, the first Sigma 28-70 f/2.8 for EOS. In this case, I can say it's optically quite good, although not quite on the level of the Canon EF 28-70 f/2.8L, especially wide open. AF is slooooooooooooooow :-), the slowest AF lens I've ever seen in my life. The AF motor is a little weak, my sample doesn't AF any more.
