The 5 in the background is obvious in the last Japanese website shot.
In fact if you look at the area under the bright edge in the top left corner there is definitely the tail of the 5 visible level with the camera body/lens line.
It\'s clearly visible in that post you point out above but the poster has not drawn a red line around it.
My monitor is calibrated so I can see it in the untweaked ones too.
