Manchester are more keen, flying out several times in the past few months and each time i left the camera body inside my bag it ends up getting flagged and then the explosives trace swab. Removed from bag with laptop / tablet and no issues.As has already been pointed out above, camera gear is not something that security officials ask you to remove from your carry on bag to put in a tray, that seems to be reserved for just laptops and tablets.
In my experience, I've only once had my camera removed from my bag and that was after it had been scanned within the bag, and they then took me to one side to go through it. This was at Heathrow Terminal 5, the security person inspected it and then took some swabs, presumably to check for explosives.
Thanks for all the feedback again
