Yes ! I have forgottent to write some words about it ! Sorry :)
They have tested the lenses in various shutter speed configuration, with and
w/o the stab, from 1/500s to 1/4s.
It's the same compensation for the IS & VR ! The VR seems to be erratic at
1/60s. Tests remade various times.
1/30s is the lowest value for both IS & VR.
In conclusion, the IS & VR have the same stab capabilities.
