Stabilized lens + stabilized body = double stabilization?

[Greg Boo]

Does the usage of stabilized lens (like Sony FE 24-70mm f2.8 GM) on stabilized body (like Sony a7c) give us double stabilization?

Will it have an advantage over non stabilized lens (like Sigma 24-70mm f/2.8 DG DN Art)?

OSS (stabilized optics) and IBIS (stabilized sensor) work in conjunction so the combined stabilization will be better than either one separately. The difference isn't huge though: remember that if the combined stabilization is twice as effective, it's only one stop. So e.g. if both OSS and IBIS give 4 stops of stabilization, the combination might give up to 5 stops of stabilization (not 8).

Each type of stabilization has its strengths and weaknesses though: OSS can't correct for roll motion but from personal experiece it's better for video than IBIS. OSS can also correct pitch and yaw motion better than IBIS, which is especially relevant for long tele lenses. When combined, you benefit from the strengths of each type of stabilization.

Hi, Just wanted to interject that the Sony 24-70mm f2.8 GM does not have OSS so it relies on the body for any stabilization. take care, Rick

If a lens has stabilization, the camera lets the lens do what it can, and will provide the stabilization modes that the lens does not provide. You do not get double stabilization.
