If you weight Sigma/Tamron lens for Canon (or Nikon) and Sony version, and if both weight the same chances are Sony version still have OS/VC built-in but the button is concealed - just a thought!

It think they wight about the same because all the bits that create the stabilization can't entirely be just removed without redesigning the entire lens, so they replace them with similar, but non stabilizing bits that just sit there, and weight a similar amount.

It would cost them more to fit the lens OS/VC with other non-functional dummy partS, especially for small run A-mount. I suspect it's something to do with Sony pressure.
