Well I own the 24-70 for my humble D3s, bought new so that is the truest indicator of my beliefs.
I am sure that is the case Rich, the D800 is even more demanding than the D3x.

My favorite lens is my 50mm f1.8 AF-D, but this simply doesn't work on the D3s in any kind of sunlight, so perhaps it is a good idea to go newer where possible.
The 50mm f1.8 is a very old design and some samples are known to hotspot in IR, that indicates to me that it may also hotspot in the visible range. Yours may be in the affected group perhaps.
How does this manifest itself Rich, Can you post an image which is affected please. Perhaps in another thread?
On the iPad so can't post example at the moment, but I did on the last forum. It's a bluish area in the middle of the image. Depending of the severity and aperture you can see the shape of the hole the blades make. Only happens with sunlight, but outside the lens is just no use with he D3s. No problem with the D200. Lens is great indoors in dim conditions, so I still have plenty of use for it.
The afd 50mm lens (both 1.8 and 1.4 variants) also suffer similarly in studio lighting with white backgrounds. I was once shooting black boots against white and couldn't stop the hotspot fogging the centre of the image.
Interestingly and somewhat puzzlingly, the super duper 24-70 has an atrocious hotspot when used for IR. it's almost 3/4 of the frame...making it unusable. I haven't considered why it works so well with colour images but fails so miserably with IR?
