All new Sigma lens have Optical Stabilisation disabled, why? crazy.

I suspect that there are several reasons:

  • cost-savings (which unfortunately is not passed on to the buyer)
  • avoids user error when both types of stabilization are enabled
  • reliability/quality are probably a bit better without the extra complication of OIS.

I have both the Sigma 70-200/f2.8 and the 17-70/f2.4-4 with OS before it was removed by Sigma. I believe that the OIS is better than the A580's SteadyShot on the longer lens but this is hard to quantify. With the shorter lens, I see no difference. Because these are my two primary lenses, I tend to leave SteadyShot disabled.
