OK, so I have taken maybe thirty shots of the facade of this building in the past two days with a variety of lenses, distances etc and this is the first shot with the D800E that has shown any moire despite my attempts at provoking it - but boy is it strong! You can just about spot it in review mode on the back of the camera so if you know it's a risk you can look for it and maybe take corrective action at the shooting stage..
Full scene (with 50 Cron R at about F5.6) then some 100% crops...
Crop from LR default. Ouch!
Crop from C1 defaults but with both moire reduction sliders full to the right:
