d4s will not show preview and will not shut off and files are corrupted.
Anyone have this problem and if so, any idea of what is causing it?
I would try a factory reset! If that does not clear up the problem, Exchange it.
I had the same problem with my images, and found out that the memory card was at fault. The card works fine in the D4 but not in the D4s. The jpegs get corrupted but the RAW are fine. About the preview, check your settings in the playback menu.
