I'm not recommending trying this but...
I came through Munich Airport this morning, feeling like death warmed up (back from India-need I say more?).
Anyway, in security I opened my rucksack with the D800 & 200-500mm f5.6 attached, as well as the 24-70 f2.8 in a compartment.
No issues, so I repacked my stuff & got the train to another terminal.
At the lounge door, I bent down to take my ticket from another case, when BANG!
I looked down, and there on the floor was the D800, as was the 200-500, no longer attached.
Then, the 24-70 hit the floor!
I'd forgotten to close the rucksack properly - doh.
I reattached the 200-500, turned the camera on, and voila - focussed & took pictures. As did the 24-70.
Hopefully I'll be taking pictures at the F1 this weekend.
But I might contact Nikon in London next week & see if they can check it over!
