Welcome to Camera Bits Forums
I was shooting with the D4s this weekend and a few weeks ago, and everything was fine rotation wise. I did notice problems with "fake" sharpness - photos seemed sharp in PhotoMechanic, but after opening them in Lightroom (or Photoshop CC) if found out that the photo is a tad more soft. Nothing catastrophic, but for the pixelpeepers it may be a problem.
I do, I thought that is the case, but it was not. Maybe it is not the PM but Lightroom problem? With D4 everything is as should be (sharpen on or off).
