"Can a DCS-930L camera owner validate whether the image zooms from the center of the video frame versus the corner. This issue was also fixed on newer DCS-932L firmware."
I do not believe that I have EVER seen that on either the DCS-930L or the DCS-932L.
EDIT: I should have been clearer! I meant I've never seen zoom from corner corner - always centered (and useless, since image is rather unclear).
