FWIW, I'm usually getting ~1/2 of the claimed IS gain based on what I consider to be critically sharp - on a fairly reliable basis that is. Of course, this doesn't mean that I don't get lucky shots beyond. I'm always baffled by the claims of some people out there but it's always the question of whether they've got the same baseline regarding critical sharpness.

Sony's IBIS is certainly not the best to start with. Oly's IS is magic in comparison for instance.

What do you think of the Sigma lens? Did the AF disappoint or is it alright?
