How does Dual IS Mode work in HS20 ?
According to the HS20 manual, when the Dual IS Mode is activated, the icon appears (icon 17 in the manual, page 5). However, I never see it in any shooting mode (P, A, S, M, EXR) or any focal length or any lighting condition or any AE, AF setting, ISO setting, Dual IS Mode is either "Continuous" or "Shooting only".
My understanding is if there is a blur warning (icon 23 in the manual, page 5), then the Dual IS Mode should be activated.
What actually the condition for IS to be activated ? Is my camera having a problem ?
